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?"
