One day five year old Johnny was at Peter's house and they were sharing a bath. So Johnny noticed that his penis was not like Peters. When he got home he explained the situation to his father and demanded an explanation.
"Well Johnny", his father said, "you have been circumcised."
"What does that mean?", asked Johnny.
"Well the front was cut off", replied his father.
"Wait a minute", screamed Johnny, "so how big was it before you cut it off?"
