I;m just looking for some laughs. What's the most evil shop prank ever played on a person. Dribble sodas...flaming tissue under chair...blued up drawer handles...etc...
Here's my favorite. Works best on real pricks. Wait till theyr'e going off in a hissy, at 7am, all bitchy, right after they get theyre coffee. Get someone to distract them while you drop 2 drops of super glue on the botton of the cup "opposite" the handle. then being all pissed off they will grab the cub too hard ripping off the handle and sending hot ass coffee right in their direction. if your lucky they'll douse the prints they are using and go atomic.
Now that's evil.
