This guy lives on the 17th floor of an apartment building. He only takes the elevator up to his apartment if it’s raining outside or someone else is in the elevator with him. If it’s not raining and he’s alone in the elevator, he gets off at the 9th floor and walks up to the 17th floor on the stairs.

Answer: He is a midget, he can not reach the 17th floor button. However, when it is raining he can can use his umbrella or if someone else is in
the elevator he can ask that person to push the button for him.
