A boy is at school and he hears the older kids talking about "pussy," and their "bitch." The boy, confused by this, approaches his mother after school. "Mom, what's a pus5y?"
The mother, startled by this, thinks quick and finds the closest dictionary and opens it up to a picture of a cat and says "Son, that is a pu5sy."
The son then asks "What's a btch?" The mother again thinking quickly opens to a picture of a dog and says "Son, this is a btch."
The son walks away still confused, and sees his father watching television. The son walks up to his father and says "Dad, what's a pu5sy?"
The father doesn't want to miss the baseball game so he quickly whips out a copy of Penthouse magazine to the centerfold, grabs a marker and draws a circle around the vagina and says "Son, this is a pus5y!"
The son, now starting to understand what the older boys are talking about asks "Then, what is a btch?"
The dad replies, "Everything outside the circle."
