An old cowboy walks into a barbershop in Montana for a shave and a haircut.
He asked the barber: “Please take a good look at my face, you would see that I have hollow cheeks.”

He replied: “Yes, I can see from this far, they are quite prominent.”

The old man: “No matter how hard I try, I never get a close shave. The bristle in my hollow cheeks always gave me a feeling that it was an incomplete shave.”

Barber replied: “Don’t worry, sir, I’ll give you the cleanest shave you’ve ever had.”

The old man sat down in a chair.

The barber after lathering his face gave him a small wooden ball and told him to put it in his mouth.

When Barber was shaving the right side of the face, he told him to move the ball towards his right cheek.

He continued to shave, after some time he said now moved the ball towards his left cheek.

The whole process continued until the shaving was completed.

Barber moved his hand all over the face of the old man, he seemed quite happy and satisfied and told him, he could take out the ball from his mouth.

The old man to check his shave, moved his hand all over his face and expressed satisfaction.

He returned the wooden ball to the barber and gave him a generous tip.

As the old man was leaving, he casually inquired: “I’m just curious if someone accidentally swallowed the ball, what would you do?”

He responded with a subtle smile: “Sir, don’t worry, such things do happen quite often, but they return the ball the next day. The ball that you have used today, was returned to me last evening.”
