A group of little boys in the 1st grade had a sex education class one day and the teacher used all the medical terminology to describe the body parts and the boys were dumbfounded as to what they meant.
When the boys went outside for recess they all started asking each other what the words meant such as breast, penis, ovaries etc. They were especially curious as to what a penis might be since the teacher had said that all the boys had one. Since no one knew the answers one of the boys said he would ask his dad that night when he got home and find out.
That night when his dad got home the boy asked him what a penis was. His dad fumbled around trying to explain and finally took his penis out to show it to his son, he said “Son this is a penis, as a matter of fact it is a perfect penis”. The boy thanked his dad and the next day at school all the boys wanted to know what he had found out. The boy took out his penis and said “Guys this is a penis and as a matter of fact if it were two inches shorter it would be a perfect penis”
