Ok, so this one is not as messy and bad as the other one. You know how they have the "Caution; Elevator Broken, Do not use" signs on the broken elevators? Well, I decided to take one of these signs of a broken elevator, post it on the inside of the door of a working elevator, might I add, and placed a video camera in the top corner of it. People go in and use the elevator, push the floor button and the doors close. "Ahhhhhh, We're going to fucking die" I heard one businessman say. when the doors closed, they saw the sign. You should of heard all the screams I got when they saw the sign. I must of watched the video over 200 times and still am not sick of it. One of the best pranks I ever pulled, I suggest you go try it one time.
