What's a bitch and a pussy?

                                        

 A boy comes home one day and runs up to his mom.

"What's a bitch and a pussy?"

"Well," Mom says, "a bitch is a female dog and a pussy is a cat."

The boy thinks to himself that this doesn't sound right since the other kids were calling each other that. So he goes to Dad.

"What's a bitch and a pussy?"

Dad pulls out his Playboy and opens it to the centerfold. He draws a circle around the woman's pussy.

"Now that's a pussy, son! And everything else is the bitch!"
