A man enters a barber shop for a shave. While the barber is foaming him up, he mentions the problems he has had getting a close shave around the cheeks. "I have just the thing," says the barber taking a small wooden ball from a nearby drawer. "Just place this between your cheek and gum." The client placed the ball in his mouth, and the barber proceeded with the closest shave the man had ever experienced. After a few strokes, the client asked in garbled speech. "And what if I swallow it?" "No problem," said the barber. "Just bring it back tomorrow like everyone else does!"
