Little Johnny arrives to school wearing a Chicago Cubs hat.
Mrs. Jones asks Little Johnny "Why are you wearing a Cubs hat?"
Little Johnny replies, "well, my mommy and daddy are Cubs fans, so I'm a Cubs fan too."
Mrs. Jones thinks for a moment and asks "Johnny, if your dad was a drug dealer and your mom was a prostitute, what would you be then?"
Little Johnny takes off his hat and replies "A White Sox fan!"
I actually saw this on a t-shirt!
