A man enters a barber shop for a shave. While the barber is foaming him up, he mentions the problems he has getting a close shave around the cheeks.
The client places the ball in his mouth and the barber 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.”
