Night Court, Season 2

Harry:
Bull, you look depressed.

Bull:
I am. My word of the month is so obscure I can't find an opportunity to use it in conversation.

Harry:
What word is that?

Bull:
"Pentimento."

Harry:
[after a beat, turns to Dan] So how about that Jets game last night, huh?

Billie:
Bull, what exactly does pentimento mean?

Bull:
It's an artistic term, referring to the reappearance of original elements that had been obliterated by a new outer appearance.

Dan:
You mean like that little brown shadow on top of your head that you affectionately refer to as hair?

Bull:
Good example!
