What does a teenage girl in Alabama give her dad on Father's Day? Her virginity
Oh man. That joke is just wrong.
It's offensive to you because it's true. Daddy likes Alabama girls more than the other states.
Making a joke about people from Alabama committing incest is pretty ignorant. While i understand the joke was simply meant to be funny, you saying that you believe it to be true could be a sign of a pretty large lack of perspective on people from the south.
