What the meanest or best prank you've ever played on a person? What the meanest or best prank thats been played on you?

I convinced my family that I was dating Elizabeth Hurley. I don't know why I did it. I was just bored. =P I had it brilliantly set up too. Whenever someone would find out, I would get them to play along with it. So, the people who knew only engrained it deeper in to the minds of the people that didn't know. I actually had a friend of my sisters confirm that she saw her one day at my house. O man, it got so crazy. My Mom kept telling me to invite her to dinner.

c/o 2003 Senior Prank: Me and three big guy friends.

We walled the principal in his office with sand bags. He opened the door to get out, and, lo and behold, he couldn't get out. The office staff was in on the prank, so they didn't respond to his yells. He went out his emergency backdoor, which triggered the fire alarm, and the whole school came flooding out behind him. ^_^

Well, it was sort of cruel, for my age.

I was about 8 and my brother was probably 16 or 17. I was with a friend of mine, and we always wanted to pull the best prank on him. One day I got a bunch of tacks, put them all face up on the bottom of the stairs, and he stepped on them..

I know, acutally that's horrible now that I think of it. He's like my favorite brother. haha.

Put crabs in someones bed.

two come to mind
1. super glued all the fingers on both hands together from that moment on nickname became flipper for him

2. duct tape someone while they are sleeping to their bed and/or bunk very common in military one for that still feel it is cruel

Gluing shut one of Moms sewing machine drawers.
She was tugging away at it then said my name.
With a butter knife and hammer she set it free. :)

In college, this one guys room was directly across from the showers/bathroom. He didn't come home one night so we moved everything in his room into the bathroom. I mean everything. Clothes, bed, carpeting, fridge,couch, curtains/blinds, posters/paintings etc. The only thing left was an old fashioned phone left in the middle of the room. Another time we filled up another guys room with crumpled up newspaper. That took a while because his door was locked and we had to throw it in piece by piece through the transom.

meanest prank i played is when me and two other friends knew that my friend mara is deathly afraid of squirrels; i kid you not. she saw one and would tear up and hypervenalate. anyways we had a sleepover and i had bought all these stuff animal squirrels and when she went to sleep we surrounded her with them. there was about 20 they were cheap $1 store toys. when she woke up she screamed, cried , ran out of her apartment and then fainted in the snow it was like 30 degrees outside. i felt so horrible later on she laughed trying to be a good sport, i ended up almost crying, i felt so awful.
