Crossword Puzzle Theme Synopsis

DOUBLE NEGATIVE: Each theme answer contains two instances of the word NO: KNOCK KNOCK, ENOUGH IS ENOUGH, and NOW YOU KNOW.

This is a fun trio of theme answers. I particularly like the classic, "KNOCK, KNOCK..." I will say that if someone were to start telling me KNOCK KNOCK jokes for hours on end, it might lead me to say, "ENOUGH IS ENOUGH!" NOW YOU KNOW. Thank you, Ricky, for this entertaining puzzle.
