This woman is visiting in Israel and notices that her little travel alarm needs a battery. She looks for a watch repair shop and while she doesn't read Hebrew she finally sees a shop with clocks and watches in the window.

She goes in and hands the man her clock.

The man says, "Madam, I don't repair clocks. I am a Mohel. I do circumcisions."

She says, "Why all the clocks in the window?"

And he says, "And what should I have in my window?"
