Dry ice in test tubes
They're nice exploding devices, where the delay in BANG depends on how cold the temperature is and how tightly shut the tubes are.

I one put about 20 dry ice in test tube tied up in a bag, in a cleaner's cupboard. The sound was just like major electrical sparking.

Soon after (half an hour) the servicing panels were all being removed whilst Estates and Services were anxoiusly checking out something. Hmm...

Here's one I did to someone who thought he was an expert
There's a setting on Windows where you can turn off items on the start menu, such as programs and shutdown. When activated, these items simply vanish from the start menu and can't be got back unless you know how.

So, this arrogant bastard was lording it over all of us in the department, saying how much he knew about computers and pissing off everyone else.

I turned off "programs", "log off" and "Shutdown" and then redirected all the shortcuts on his desktop to a simple dialogue box program which just displayed "You must reboot your computer to correct the error that has occurred." - needless to say, as the desktop was set up like that when he turned the power off and then rebooted, it came back in exactly the same state.

It took him nearly a whole day to ask for help, and nearly another whole day before any of us were free enough to help... revenge was sweet!

My parents told me...
...that when i was a baby (i dont remember the incident) our oven in the kitchen downstairs, blew up, while i was fast asleep in my cot upstairs. Apparently i had managed to work an aerosol can to the back of the oven and when my mum went to cook dinner that night... it didnt take long and BOOM!

On a plus, the oven was old and they got a nice new one from the insurance.

Computer sabotage by accident...
Back in '93 in my last year of college I was in the computer lab a week before midyear exams, at the time we had a mixture of Archemedes and BBC Model B Micros which were both connected via the same network (Econet for those that remember) I managed to break out of the login/network boot process and due to a bug on the Archimedes RISCOS Operating System I mistakenly reset the public user accounts password(one thats used for booting the machines) - Well to be exact, I gave it a password - its usually passwordless. This shouldnt be allowed to happen. I wasnt actually trying to do this I jus tthought it'd be a laugh if it actually worked - and it did..

Consiquently I set it to something I didnt know cause I figured it wouldnt take. the password was longer on the Archs than the BBC B's could handle so no BBC B users could login anymore and the arcs would ask for a password at boot.

Imagine the chaos of students who werent able to login to do their revision, and due to somebody seeing me messing around they soon tracked it down to me - only time a teacher has threatened to punch me!

I managed to get away with no reprimand on my school record and I heard it took them 8 hours restoring from floppies to remove the password from the boot drive..

OOPS..

Still I look back and laugh..

Oh well :)

Computer/office fun
My best must have been throwing a colleague a can of 3M Spray-mount (basically an aerosol of glue) when he calls over for some screen cleaner.

He really did spray his whole monitor before noticing. This started a small war of petty computer crime between us (we are mates) including hacks that made everything in the OS appear backwards like arabic, bluetoothing swearwords to each other, stretching elastic bands across everything on his desk (took about an hour to get the space usable again and similar petty-but-funny-ness.

Eventually it just descended into a war of raisins fired from catapaults made from bulldog clips, elastic bands and slivers of drinks bottles. More lethal than it sounds. He's left before Xmas but his laptop says "Big Dog's Cock" at startup instead of "Mac OS 9" (in the correct font naturally) after my witty ResEdit shenanigans...

Oh! Oh! My canadian friend at their equivalent of the BBC has a boss she really hates and somehow manged to pee into an atomiser bottle which she now sprays onto phone reciever, keys and seat when the boss has buggered off early. That is a winner I reckon.. :)

Check, mate
After two terms of having a really great, slightly mad English teacher, he went on Sabbatical, leaving us with a totally out-of-her-depth sub. We broke her in three weeks.
Our desks were in a big horseshoe shape, she liked to prance around and lecture from the middle. Over the course of a double lesson we slowly moved all the desks towards the centre.
She turned around to find herself wedged between three tables. Properly stuck. We didn't let her out at the end of the lesson. I think she actually cried tears of rage.

Mark this
One of my maths teachers (Slow Joe) used a different coloured marker for writing on the whiteboard depending on context, something like:-
Black - question
Blue - working
Green - answer
Brown - theory/hypotheses
Red - proof

I once got to class early, no-one around, and decided to have a little fun. Yawn, you say, swapping the caps is hardly imaginative. But I didn't, no, I unscrewed the nibs and swapped the bases - the cap and nib were one colour but the ink in the reservoir was another.

Lesson starts, he picks up the black marker and starts writing - black at first, gradually getting lighter and ending up brown. Blue goes purple then red. And so does my maths teacher. He goes abolutely mucking fental.

I eventually had to own up to avoid getting a friend in trouble but when I reported for punishment my housemaster was too busy trying not to cry with laughter to bother, Slow Joe being as popular in the staffroom as he was in the classroom.

We also once tried the watercress-on-the-carpet trick at Uni, but it didn't sprout it just rotted so when the guy got back after a weekend at his parents, his room smelt so bad even after the carpet was taken up and dumped that he was re-housed and his room was boarded up and never used again (the whole house was condemned anyway).

Presumably this QotW will be won by Rossi and Parfitt for revealing that they superglued the Titanic's rudder, removed the "No smoking" signs on the Hindenberg and cut the cables marked "Tsunami Early Warning System' during their recent tour of Indonesia.

Whilst at a student party in my University Days, noted that someone hadn't taken their clothes out of the washing machine, which was a bit foolish really, at a party.

So I open the drawer where you put the detergent, empty my bladder into said receptical, shut it and set to wash.

can't tell you the results as it was one of those random parties that you end up at, but it kept me smiling for weeks.

I once slipped a pound coin
into my girlfriend's burger when she went to the loo in the pub.

Don't know what I thought would happen but I could hardly contain my excitement when she came back to the table.

She took a big, confident bite - then squeaked and spat out a lump of burger, a quid and her front tooth.

Laugh? I nearly bought a round.

Powder pepper
I hated my brother when he was younger. All sorts of reasons, but there you go.
One thing I particularly hated was his pretentious use of that horrible ultra pre-ground black pepper, from his own personal shaker. He put it on everything. All over covering everything.
How to sabotage this? I noticed when cleaning my electric shaver that the mottled 'beard dust' that collects in the blades looks just like his pepper. So I started saving it up.
After a month or so I had lots of it. I half emptied his precious pepper shaker and filled the rest with my nausiating beard trimmings, and shook the container up.

Come the next meal he covers his food in 50% pepper, 50% facial hair, and didn't notice.

I kept refilling it like this for months, and started enjoying mealtimes a lot more.

I've never told him, and, for those who are concerned, we get on much better now, thankyouverymuchly.

In the office I used to work in, the cleaner was a total bitch.
Every day she would moan at me for filling the (communal) bin. With rubbish, no less.

Every day for three months at about 3pm I would go into the loo and see her using her fingernails to pick 'soap spots' off the mirror.

They weren't soap spots. They were my big, snotted out bogies.

Take one golf ball
and pop it up the exhaust of a car and poker it through into the muffler. As the car starts the air pressure forces the ball into the pipe and stalls the engine, whereupon it falls back into the muffler.

After about five restarts the white outer casing will start to melt and as it does so the interior of the ball (a few hundred feet of elastic) melts and gums up the exhaust system permanently.

Warning: Only do if you really, really dislike someone.

You can get away with so much.
When I was really young,my mom made my big sister look after me. After years of her bossing me aroung- playing Captain Planet, where she got to be the one from the Soviet Union, and I had to be toxic waste,then Bucky O'Hare where she got to be the pink rabbit with the jewel thing on her head, and being relegated to the role of Skeletor again and again I finally got my revenge when she got her first boyfriend. I sat down and told him about how She used to poo behind the telly when she was a toddler,and post toast into the VCR (but then,who didn't do that?)and how she once ate a cheese plant because she thought it was real cheese.
She's never forgiven me.

One day
I got angry with filly that I had been bonking so proceeded to tamper with her oscillating sex aid. Armed with the secret weapons of chocolate, a nail file and 22.5 inches of red from the pick and mix I rigged the thing to blow. My handywork was undetectable as she fondled its purple rubberyness, and with a certain degree of numbskullery she jammed it in her pastrami curtains.
Success I cried as the motor roared into life and drove the weapon of sodomy right up inside her. Quick as a flash I grabbed a 2 by 4 and nailed it between her legs so the bomb was hidden away inside. The resulting explosion triggered a fanny fart so powerful she travelled right round the moon and off into a black hole.
It would be the last time a wench would even think of trying to outsmart this genius of fox like quality.

Revenge of the Nerd
A rather annoying quarterback from our high school team (notice I did not use the term football to avoid confusion) had a high opinion of himself and his brand new (mommy and daddy puchased) Mustang. After observing with great disdain his constant bragging regarding the car's and his performance in various situations I devised a lovely bit of justice to be wrought upon him.

After purchasing a propely sized whole frying chicken from the local market, I carefully crawled under said Mustang and stuffed it on top of the magnificent high-flow muffler under the middle of the car. (All done during practice of course to prevent an altercation.) I secured the now hidden chicken with a wire coathanger to ensure the longevity of its stay.

The next morning at school, imagine my delight when the arrival of our hero is announced by a lovely baked chicken smell - quite powerful. And then try to suppose my glee when his tiny brain failed to discover our fowl friend for 5 days thus rendering it foul indeed and increasingly moreso until it's discovery in a mechanic's shop and a $200.00 bill to have it detailed to remove the stench.

Apologies for length... but it was good to finally tell all.

Sab life
This one still brings an evil grin to my face - even after 10 years.

Stood in Woolies with a mate - at about the age of 16, youthfull looking scallywags we were too. As I'm sure all of you of a non-colonial nature are aware all Woolies have a big pick and mix station near the cash registers.

A mum and kiddie wandering around looking at the plastic tat on sale - kiddie looking very bored. Cue me turning and saying to my mate in a fairly loud voice "You know, so long as you eat them in the shop, the pick and mix is free, you can have as many as you want."

The little glow of joy from the kiddies face was somethig to behold - mate and I departed to another bit of the shop to watch the young scamp start to fill his face with assorted chocolate goodness.

I couldn't have predicted that he and his Mum would be escorted from the shop? Could I?

His little cries of confusion as his Mum yeled at him still make me laugh today.

Pop, there goes another board virgin.

hmmmm -
technically more a fraud than a prank......

After leaving uni, i did the obligatory stint at a local supermarket whilst trying to find a proper job.
Anyway after a couple weeks I somehow managed to get put in charge of the night shift.
This entailed checking the days stock sheets etc and verifying that the delivery matched up.
I also had to update the stores stock system.


So I found out that I could add a couple of extra cases of booze etc to the next nights delivery, then the next evening I would call the main depot and check that the lorry was loaded - then I could cancel the couple of cases on the system.
The delivery note didn't show em, and they turned up at the store for me to pass over the wall to my mates :)

Apologies for teh length but it might help a few poor supermarket employees out there.

My fave act of sabotage!

Method:
Get a large bin (like a wheelie-bin), fill it two thirds full with water, empty a packet of water-cress seeds into it, and lean it at 45 degrees against someone's door while they are in their room (NOTE: the door opens inwards, right? I dunno why but doors almost always do).

Result:
When the victim opens their door the bin will fall inwards, flooding their room. Ha ha. End of joke, right? Wrong! A few days later their still-damp carpet will start sprouting a forest of lovely fresh green shoots :-D

Hair Sabotage
After a spate of viscious rumours about myself, I finally tracked it down to a girl who was jealous of my boyfriend.

I had known this girl from school and she was very proud of her really long hair.

After several weeks of waiting for the perfect oppourtunity I quietly stood behind her and emptied a bottle of superglue into her hair in a nightclub.

Then the joy to see her the next week with short hair and a really sad face!!!!

More than petty
My personal account is minor: a few keyholes glued shut with a concoction of wet toilet paper, stealing important transparencies from my teachers and binning them, putting the birth control pill into my (male) history teachers drinking water, drive by 'eggings' onto various cars and businesses, you know, fun stuff.

My best fried, however, has the award for most expensive act of vandalism ever. One drunken evening she came home to discover that her hated next door neighbour had just repaved his driveway. So, in her brilliance, she removed the paving to a more suitable location.

The body of his car.

It was quite an expensive car too. Bless her, she's such a lovely girl.

Added Exam Stress
Just before one of our friends 3 hour Technical Drawing o level a couple of us who didnt take that subject bet the guy 1 pound each in a pint of water drinking race . He quickly finished his winning the bet so we called for a rematch , then again , then again . Ok it cost us 4 pounds each but it was hilarious to hear reports from others taking the exam that he had to leave the exam room for a piss so many times that the teacher thought he must be cheating .

office fun..
all this was done, by me, in the first month or so on a new job

lock co-workers phone in their drawer. take the key. ring thier phone

swap the n and m keys on their keyboard over. works best if their password has m or n in it

turn everything on a co-workers desk upside down

on some mouse drivers there is an option to set the orientation of a mouse. turn the mouse back to front (or something) then set the orientation

turn everything on a co-workers desk upside down. not subtle, but fun

tape the handle on the bottom of someones chair to the up position, so it rises whenever they stand up and sinks whenever they sit down

stealing mouse balls *snigger)

net send

setting monitor darkness to 'nothign'

plugging their phone into the network and visa versa (both run off rj45 here)

swapping peoples phones over (long rj45 leads) so they all get the wrong phonecalls

more may follow..

badabupbabaaaaaa.... i'm loving it!
There was a bloke at college no-one really liked, we just put up with him being a twat. It might've been the fact he wore his long ginger hair in a ponytail, or that he had a hat that looked like a load of socks tied together that he always wore.

In college we all had set drawers for our work and one day his folder and all his work were missing and he got in trouble with the tutor as he never really did much work anyway.

He didn't know but I had put all his work in a different drawer - another bloke found it an hour before hometime.

This went on for a few weeks with me hiding it in various parts of the room, and he alsways asked me if 1) i knew where his work was, and 2) who was moving it.

I obviously denied all knowledge.

The last thing i did before leaving college was move the polystyrene ceiling tiles and put his entire 2yrs of work in the ceiling space!!!!

Ahh how i chuckled. Best bit was the entire class knew i was doing it, the tutors knew i was doing it and everyone went along with it
