What did you do to push someone over the edge?

I photocopied a paperclip a hundred or so times, put the pieces of paper back in the drawer,

so whenever it's used, the documents have a paperclip on them.

My office went nuts, took it apart trying to find the paperclip stuck in the machine.

They even called in a technician.

Laughs were had. Glitter. Everyone hates glitter. I came up with this prank a few years ago.

Every morning I'd take some glitter, which conveniently came in little vials and poured some

into my roommate's pants pockets while he was out of the room. Usually, I could tell by his morning routine

which pants he was going to wear for the day. But even if I got it wrong, those other pants

would be primed for the next time he wore them. All day, he, like everyone else on earth,

would put his hands in his pockets to get his phone, keys, or just casually, thereby transferring

a little glitter to his hands. He would then touch his

shirt, pants, and or face at some point. For two weeks, people would tell him that he had glitter on him,

but he was never able to figure out where it was coming from. After going on a rant about how

confused and utterly crazed by the sudden appearance of glitter everywhere he goes he was, I came out

and told him that it was me. I could have easily done this for a lot longer since he never figured

out the glitter was in his pockets, though I became very liberal in the amount that I poured in.

When I worked at a banquet hall in a hotel, I had a manager who who we'll call Steve, who treated everyone like crap,

calling us stupid, calling us out on things, not even the managers above him cared about, and just

generally being a butthole. One day he put this annoying memo on the bulletin board about not

eating leftover food. None of the other managers cared about this and it actually went in the

garbage if no one ate it. But instead of signing his name, he put banquet management. Well, as a joke,
