Watch Repair Shop

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?
