Circumcision Conversation

Two young boys in the Middle East just turned thirteen. Ali was Muslim, and David was Jewish, but they were very good friends.
One day Ali mentioned to David, “I’m getting operated on tomorrow.”
“Oh?” said David with surprise. “What are they going to do?”
“They are going to circumcise me,” said Ali.
“I had that done when I was eight days old,” remarked David.
“Did it hurt?” asked Ali.
“I couldn’t walk for a year,” said David.
