Solution to Puzzle #4
This guy is a midget (little person for the P.C. crowd) and can only reach to the 8th floor button. On rainy days he takes his umbrella to work which he uses it to push the 20th floor button when he comes home.
The Man who Hanged Himself
Not far from Madrid, there is a large wooden barn. The barn is completely empty except for a dead man hanging from the middle of the central rafter. The rope around his neck is ten feet long and his feet are three feet off the ground. The nearest wall is 20 feet away from the man. It is not possible to climb up the walls or along the rafters. The man hanged himself. How did he do it?
Hint #1: The man acted alone. There wasn't any other person or animal present when he hung himself.
Hint #2: The roof was completely intact. i.e. no holes.
