Quote from Adam in The Hooters
Mr. Crosby: And remember safety first. There's no room for tomfoolery, shenanigans, or joyful horseplay in this class. All: We'll cut off our finger. Mr. Crosby: And why do we always measure twice? All: We'll cut off our finger. Mr. Crosby: And how do we know this to be true? All: You cut off your finger. Mr. Crosby: That's right. I cut off my finger. And this one! This one they sewed back on, but it doesn't work right. Finger rejected the host.
