A man walked into a small shop that had hundreds of watches and clocks in the front window. He produced a wristwatch from his pocket and placed it on the counter in front of the shopkeeper.

"I'd like to have this repaired, please."

The shopkeeper looked at him oddly and said, "We don't repair watches here."

Surprised, the man asked, "If you don't repair watches, do you sell them?"

"No." The shopkeeper replied.

"Well!" The man said with a growl. "Why, then do you have so many timepieces hanging in your front window?"

The shopkeeper answered, "I do circumcisions. What would you put in the window?"
