A man enters a barbershop 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 the man 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!”
