Pranks
From the innocent to the extreme. What are the funniest pranks you've pulled off/witnessed/been victim to/thought about/ect.? Preferably not stuff from movies.
Thanks

that is honestly hilarious. i wish i drove on that road.
Porn pics in peoples' printers is fun.
A fellow I know photoshopped a guy's face into a porn picture of someone getting Eiffel Towered, with his mom and sister's faces on the other two people in the picture. Then he plastered the pictures all over the guy's bedroom while he was on vacation, thinking only the guy would see it when he came back. But the guy brought his mother and sister into the room to help unpack and apparently things were awkward.
Also when he lived in residence my boyfriend taped a bowl-chair full of water to someone's ceiling. They knocked it down and water went EVERYWHERE. Then what's more he and his friends stole some official residence stationary and kept sending the girls who were pranked all these letters about how they owed 5000 in water damages and were being evicted.
The fuck's a bowl-chair?
This is why we can't have nice things.
I made that name up for it. It's a chair that's... kinda shaped like a bowl?

Comme ca, only the prank ones were solid plastic instead of gappy wicker, hence the ability to hold water.
what is "getting eiffel towered"

I signed my friend up for free tampons in the mail. Then he had to stand in line at the post office for 30 minutes because the tampons didn't fit in his box.
My friends downloaded a sign up sheet for NAMBLA and filled it out with their roomates info all ready to be mailed and put it right on his bed when he was out on a date.....needless to say when he brought his date back to his room she found it and was like "What the hell is this about?" There was some explaining to do.

Last year in Downtown Austin someone reprogrammed Road Work Signs to warn people about Zombies. I think it was about 10 signs or so right along Hwy 35 and they were all up during rush hour. I don't think they ever found out who did it...
