This reminds me of another newspaper prank, which I heard of from an old friend who attended the U. of Rochester in NY. A guy who lived on their floor had the Wall Street Journal delivered to his door every day, and the others on the floor decided to poke fun at this upscale practice by sealing off his door (from the outside) with sheets of the Journal. Every morning, the guy would open his door, see the doorway blocked by the sheets, and leap through. This became a morning ritual. One day, somebody got the bright idea to put a Coke machine on the other side of the papers, and the guy got a concussion when he tried to go through.
