Actually years ago the joke was just the opposite...something like...
A child goes to the police station claiming abuse
The officer says, can I take you to your parents.
The child says, no they beat me.
The officer says, can I take you to you grandparents
The child says, not they beat me as well.
The officer says, well where can I take you?
The child says, take me to the Buffalo Bills, I hear they don't beat anyone...
