A man was once walking and noticed a little store with a bunch of watches and clocks hanging in the window. The man walked in and said "Can you please fix my watch ?"
The Guy behind the couter quickly responded "Sorry but I don't repair watches."
The confused customer said back, "YOU DON'T REPAIR WATCHES?? WHAT DO YOU DO??"
"I'm a Mohel"
Now even more confused the man asked, "If you are a Mohel, then why do you have watches hanging in the store front???"
"What do you want me to put in the window?"
