Put my beard on again

A man who sold brooms went into a barber's shop to get shaved. The barber bought one of his brooms, and, when he had shaved him, asked for the price of it.

"Two pence,"said the man.

"No, no, "said the barber, "I will give you a penny, and if you do not think that enough, you may take your broom again."

The man took it, and asked what he had to pay for his shave.

"A penny."said the barber.

"I will give you a half-penny, and if that is not enough, you may put my beard on again."
