A: Did you see my new shoes? I remember putting them on the corridor.

B: No, I didn’t.

A: Ugh, your puppy did a number on them — they’re completely chewed up!

Note: It’s a slangy term meaning “to damage or harm someone or something.” The origin of the saying dates back to the 1960s as boxing had growing popularity. The saying refers to how different types of punches were assigned different numbers. Announcers would say this when a fighter was dominating his opponent. It is now used in a more general sense.
