A man stands in front of an open elevator and there are two men inside. The two men inside the elevator are wearing suits and have large tuba instruments wrapped around their body. One of the two men wearing a tuba has glasses and the other has a worried look on his face.
Tuba instruments are large and you don't see people carrying them around their waists as they ride elevators.
Why are the men wearing the tubas?
No, you come in on four.

A play on the phrases "come in" and "four" --- if a marching band were practicing their routine, they would probably discuss particular beats on which instruments "come in," or join the piece (e.g., "on [beat] four"). But in an elevator talking to the person trying to literally "come in" to the elevator, on "four" refers to floor four: the phrase would mean that the person shouldn't enter the elevator on the current floor because it's not the fourth floor.
