In 1968 I lived in a dorm with a genteleman who ledge walked to the open window of his neighbors dorm room (3rd floor) and climbed in.
He then tied a rope arond the guy's mattress and attached the other end to the door knob.
The mattress was then lowered out the window and the hinges were removed from the door ... he left the same way he came.
Nearly pull the guy's arm off when he unlocked the deadbolt and turned the knob.
I like the idea of taping FAX spams together to form a continous loop and sending back to the sender...
