A rather pompous fellow lived in our dorm in college. A personal feature were his keys, a big ring of them, attached to one of those chains that retract into a sping-loaded metal cannister attached tohis belt (firmly attached . . ) Aided by his long-suffering roommate, we got into his room after nightfall before his return, hung his desk out the window and attached it by means of a rope to the doorknob across the room. We then pulled the pins from the door hinges, pulled the door back into its frame, and locked the deadbolt so that it was the only thing that was holding the door in place. Dashed to my room (adjoining), and listened. Sounds of his feet in the hall, key in the door, some struggle with the lock, then (in rapid succession) the lock opening, the door crashing inward and sliding across the room, the crisp zip of a key chain being fully unwound from its canninster and th shout of surprize as the wearer is pulled after (dont woory,the door stops at the window.
