riding a phrase

when someone uses someone else's answer that they have heard before to a question they were asked, especially if it was a smart/witty answer.

john: "so how are things working out for you with jane?"
bill: "we're fine as two fine things on table."

after a few minutes.

kurt: "how are the kids?"
bill: "they're fine as two fine things on a table."
kurt: "hey! bill said the same thing to me earlier. don't go riding a phrase, bill."
