Quote from Michael Scott in The Sting
Michael Scott: On the count of three, it's showtime. Ready, one, two-- Jim: Nope, not doing that. Dwight K. Schrute: I've been in showtime mode since breakfast. Michael Scott: Okay, you know-all right, just forget it then. Jim: Showtime! Michael Scott: It's showtime! Oh...never mind. Let's go.
