Jokes - A kid comes home from school

A kid comes home from school and says to his mom,

"Mom I've got a problem." She says, "Tell me." He tells her that the boys at school are using two words he doesn't understand. She asks him what they are. He tells her "well, pussy and bitch." She says, "Oh that's no big deal, pussy is a cat like our little Mittens, and bitch is a female dog like our
Sandy."

He thanks her and goes to visit dad in the workshop in the basement. He says to his dad, "Dad the boys at school are using words I don't know and I asked mom and I don't think she told me the exact meaning." Dad says, "Son, I told you never to go to mom with these matters, she can't handle them.

What are the words?" He tells him...pussy and bitch. Dad says, "OK," and pulls a Playboy down from the shelf, takes a marker and circles the pubic area of the centerfold and says, "son, everything inside this circle is pussy."

"OK, dad, so what's a bitch?" "Son," he says, "everything outside that circle."
