More Natural Justice than revenge, but hey...
Shared a farmhouse at college with 4 other mates in our second year. In the first year we all got on fine, but then we weren't living together then...
One of the five was an only child, and the apple of his wealthy father's eye. This farmhouse had no heating (other than open fires) and only an outside bog. The hot water heater for the bath never worked in the year that we were there, had to use the showers at the college gym. Yes it was up north, students were harder then...
Spoilt lad of course has a big electric fire and electric blanket etc which were left on morning noon and night. We used to turn them off, he'd turn them back on. As we had previously agreed to divide all the bills equally we were a little unimpressed, especially as his "daddy paid".
One lad had a mate from home come to stay, and she was a gorgeous nurse, and an unshockable one too. Needless to say spoilt lad, who was a handsome devil and used to getting his way with women took a shine to her. Bless her, she was having none of it. The last morning that she was with us we were awoken by an outraged scream, she'd tied a pink bow round his knob while he was asleep. He put a lock on the door that same morning.
One of the crew was raised on a farm on a diet that contained plenty of unpasteurised milk etc, so food poisening was a foreign land to him. Every day when he came in from college he used to get the frying pan and concoct a student meal which became known as onions, rice and shit, (the shit being anything else he could find in the fridge). This one time the shit was some very old sausages. Spoilt lad comes through the kitchen and helps himself to a piece of sausage from the pan while farmboys back is turned. Within the hour spoilt is shitting through the eye of a needle and being copiously sick in the lean-to basher while farmer has eaten the lot with no ill effects.
Spoilt had an obsession with Bladerunner and when it came on the telly we were all sat round to watch it (first TV showing I think) AND he's got the VCR set up to record it. He'd been boring us about it for weeks. Half way through the telly goes of as does the video. Spoilt goes frantic. He goes to check the fuses, sure enough one is gone, so he replaces the fuse wire and puts it back. POP. Repeat. POP. Oh dear. By now he is beside himself. Once we were sure that he was close to giving himself an aneurism one of the lads went upstairs and removed the plug with the live shorted to earth that he'd put into a time switch several hours earlier...
I could go on cause there were loads of these little games, but that was probably the best of them.

Further to the Onions, Rice and shit story, the farming lad never ever did the washing up, never, not even once. When we started to get on his case about it he calmly took the washing up bowl outside and shot it several times. (We had a shooting gallery set up on the top corridor, hence the gun).
When he got home from college the next day we had prepared his O,R and S for him already, except that the shit was manure harvested from "Gusto", the lonely pony in the adjoining field. Farmlad just emptied it into the bin,gave it a half hearted rinse under the tap, and cooked his dinner in it, again with no trace of ill effects. Bugger.
