You Can't Do That on Television, Season 8 (1987)

[Mrs. Prevert is washing a stack of books in the sink.]

Adam:
Mom! What are you doing?

Mrs. Prevert:
Oh, hello Adam. I was just washing some dirty books I found in your father's closet.

Adam:
Mom, you're ruining them!

Mrs. Prevert:
(faking concern) Oh, am I, dear?

Adam:
You're doing this on purpose, aren't you? I'm going to go tell Dad.

Mrs. Prevert:
That's a good idea, dear. While you're at it, why don't you tell him that I just finished washing the dirty books I found in your closet. Your father would probably be very pleased to know that you have similar tastes in literature.

Adam:
...Okay, maybe I won't then.

Mrs. Prevert:
Wise move.
