Joke

A man is wandering around town when he notices his watch has stopped working.
He comes across a tiny shop window with a display of clocks and watches so he goes inside.

He asks the clearly Jewish proprietor if he can fix his watch.

"No", he says, "I don't do any thing like that."

Confused, the man asks why he has a window display of clocks and watches but doesn't do that sort of work.

The proprietor replies "I'm a a doctor. I perform circumcisions. What would you like me to put in the window?"
