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. 

 

            &quot;I have just the thing,&quot; says the barber taking a small wooden ball from a nearby drawer. &quot;Place this between your cheek and gum.&quot; 

 

            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. &quot;And what if I swallow it?&quot; 

 

            &quot;No problem. That happens from time to time,&quot; says the barber. &quot;Just bring it back tomorrow like everyone else does.”
