A man lives on the 66th floor of an apartment building. When he goes to work on sunny days, he takes the elevator all the way to the ground floor. When he comes home, he rides the elevator to the 36th floor, then takes the stairs up the rest of the way to his apartment. But on rainy days, he rides the elevator all the way up to the 66th floor. Why?
He’s extremely short, and has an umbrella on rainy days to press the higher button.
