Guy goes to a barber to get shaved

He sits down, the barber hands him a small wooden ball and says: “Put this inside your mouth. Left cheek first, then right. It’ll stretch the skin so I can shave you clean.”

The guy nods puts it inside, but then asks: “What if I accidentally swallow it?”

The barber shrugs and says: “Eh, no problem. Just bring it back tomorrow… like everybody else does.”
