- —Mike Wazowski, explaining why he was yelling
"Put That Thing Back Where It Came From or So Help Me" was originally a fake play invented on the spot by Mike Wazowski as he and Sulley were attempting to return Boo, a human girl, back to her room and were nearly caught by other members of the company. It was later turned into a real play that was performed at Monsters, Inc. at the end of the film.
