A man enters a barber shop for a shave. While the barber is foaming him up, he mentions the problem he has getting a close shave around his 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 places the ball in his mouth and proceeds with the closest shave he has ever experienced. After a few strokes, the client asks in garbled speech, "And what if I swallow it?" "No problem" says the barber. "Just bring it back tomorrow, like everyone else does!"
