Joe enters Mark's barber shop for a shave.
While Mark, the barber, is foaming him up, Joe mentions the problem he has getting a close shave around his cheeks.
"I have just the thing," says Mark, taking a small wooden ball from a nearby drawer. "Just place this between your cheek and gum."
Joe places the ball in his mouth and proceeds with the closest shave the man has ever experienced.
After a few strokes, Joe asks in garbled speech "And what if I swallow it?"
"No problem" says Mark. "Just bring it back tomorrow like everyone else does!"
