a man enters a barber shop 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 he 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!"
