Okay, folks! I've got a "fill-in the type" of question.
The Question is: What do you call that thing where you remember that thing from years ago and finally come up with a really funny response to it?
Okay, you fill in the rest with your own response. (whistling, "I can wait" and . waiting)
To start things off, I'll provide my own answer, but then you follow along and supply your own answer to keep the ball bouncing.
My Answer:
Oh, what about "retarded"?
