Ok, practical jokes, lets here what some of the pranks or been pranked that you've had in the past.
Late last night/early this morning, one of my roomates came home ready for sleep after a long day at the studio, only to find a 4 foot tall, 300+ lbs log in his bed
It had been an elaborate scheme involving creative camera angles, dressing up of the log including hair and sneakers, and an all around "dude, there's going to be a HUGE fucking log in his bed, he's gonna be SO pissed."
Needless to say, we hear "WHAT THE FUCK! YOU ASSHOLES, I'M MOVING OUT! I'M NOT EVEN JOKING!" We then hear glass shatter, and a few threats to be stabbed eminating from his room. Good times had by all.
Oh yea, we also paid a kid 4 bucks to poop in a cup, then ride up and down in the elevator, along with two of our friends who were wearing only T-shirts, socks, and sneakers. All videotaped, of course.
