We had a very posh (in the bad meaning) and nerving girl in our group. She was a friend of a friend of a friend (know what I mean?), and nobody knew why she was still there. Hmm... well, she tended to talk rubbish and little lies, just to look better in front of the other people, and so there was a need to make her a bit smaller

An ex-boyfriend of hers told me of her arachnophobia, so I folded a tiny spider, that should fit into a matchbox. I took a small spring and glued it into that matchbox. Then I placed the spider onto the spring and glued a additional dividing wall into the matchbox (so that the spider wouldn't move inside the box). I pushed the spider down and closed matchbox *harrr harrrr*. of course you know what happend

On the next group meeting, I replaced her matchbox with mine and waited. As she opend the box and the spider "jumped" out of it, it was like a sirene would start to yell. She jumped up and ran out of the room. She didn't liked me anymore from that day on, but I got some beers for free because of that

Does anybody else have had an origami revenge or something like this?
