Try it before you share
Repooc's post reminded me.

Many moons ago, I was working in admin for a fair sized company and shared an office with a few other first-job teenagers.

As this was before youtool or facepunch, many jokes videos pics and links were passed around via our work email. One of the few memorable ones was a 'quiz' of the girls magazine type which was to make your lord of the rings character name or some such guff. It was fw'd around by Jill, the young stereotypical blonde.

The link was actually a cunning trick which asked several inane questions but only picking up the name and maybe gender. Clicking on submit would make your full screen flash magenta/cyan with large yellow text stating
PERSON LOVES BIG HARD COCK UP HIS/HER ARSE while disabling all mouse and keyboard functions except, I gladly found, ctrlaltdelete.

I don't know who was most beetroot, Jill or Stephen (the most severe 18 year old closet case ever)...

Which reminds me....
Of a similar one that went round our office, again this doesn't show IT people in a brilliant light, but for the record it didn't get me.

It was an executable (I know, don't even go there!), all it seemed to do was pop up a box saying "You've been bearded!" with an OK button.

So you thought nothing of it, walked away from your machine and when it locked automatically your desktop wallpaper was the biggest hairiest fanny you'd never wish to see in extreme close up.
