He said, "I know what you can do. You can shave off your hair to start with." Then later on I had to shave off my poor mustache. I had to shave it off right down to the skin.
Curly Howard: Sure it hurts, especially if Moe lands a little low when he slaps me. If it's on the cheek, it's all right. But if he gets me on the jaw then I'm apt to have a headache for hours.
Curly: Rrrowf! Rrrowf! (angry).
Curly: La-la-la, la-la-la..., (Curly humming).
