A man is walking down the street when he passes a store front with a large watch in the window. He enters and asks the storekeeper if he could fix his watch. "You want I should fix your watch?!" the storekeeper exclaims. "Yes, aren't you a watchmaker?" asks the man. "A watchmaker?! No, I'm a mohel!" "A mohel!" exclaims the man. "If you're a mohel, then why do you have a watch in your window?" "What do you want I should put in my window?" says the mohel.
