Second Hand Material

To reuse a joke that was already said earlier, but is still as funny or funnier the second time. It could be so funny, that it will become an inside joke.

LOLL!
Thursday: Hey Kat, I have skittles in my mouth... wanna taste the rainbow?
DOUBLE LOLL!!
Kat: You just used second hand material you bitch!
