What was mine? Well, one day I found this old jar of mayonnaise in my house. Given that it was almost past it's expiration date, I was going to throw it away, but then I got an idea. I emptied out the jar completely and then I made Vanilla pudding. I put the pudding in the jar and then I went outside. I went to the subway terminal, took a spoon, and started eating the white Vanilla pudding out of the Mayonnaise jar, making it look like I was eating spoonfuls of mayonnaise! The reactions I got from people were hilarious. They didn't speak up, they just stared in what seemed like a combination of amazement and sheer disgust. I was almost crying from trying to hold back my laughter and keep my poker face. It was one of the best days of my life! Now tell me yours!

Oh, Lord. I have done so many of them. Some original, some I got from other people. Here is one thing that I have done that was pretty great (I did not come up with this, unfortunately). I got a hold of some non-colored gelatin. I boiled it in water, and then poured it into my friend's toilet. The important part is to not fill it too much or the toilet will flush by itself. When the mixture cooled, it is pretty much colorless jello. My friend took a number 1 and 2, and realized it was all just sitting there, and he couldn't flush it down. The water just kept flowing because it wasn't going down the drain. It overflowed, and he had to use his hands to scrape out the gelatin along with his own waste to get the toilet to stop flowing. To this day, he does not know that it was me who did it.

Now if I wasn't on such thin ice with my step mom I would do that Mayo trick on her.

Ok my senior prank in high school~~

I had a big group of anime/gamer friends and we all were into .hack// series.  The website had a little flash video that made it look like your computer was being hacked.  So (now I forget how exactly we did this it was a long time ago) we were able to time it exactly so all the computers that were on in the computer lab ran that video full screen.  The computer lab teacher FREAKED!  Until he saw the rest of the video which showed that it was just a video.  Funny thing is this was my computer programing teacher so I got extra credit for the year for designing this prank with my boyfriend and other friends.  Funny as hell prank and I got extra credit out of it!

An aquantence was having a small party. So we handed out flyers to random people in the town he lived in. Ended up being a party of the hugest magnitude and everyone had a good time. His parents house got trashed/looted so it was also one of the most horrible things I have been a part of. He didn't mind though because it was the best party ever.

This thread has long been inactive. Also I'm pretty sure it's a dupe. Either way, I'm closing it.
