Two five year old boys are standing at the toilet to pee.

One says, "Your *thing* doesn't have any skin on it!"

"Of course, not! I've been circumcised."

"What does that mean?"

"It means they cut the skin off the end."

"How old were you when it was cut off?"

"My mom said they did it on the eighth day after I was born."

"Did it hurt?"

"You bet it hurt! I couldn't walk for a year!"
