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. 

"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 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."
