A cop pulls over a carload of nuns.
"Sister, this is a 65 MPH highway -- why are you going so slow?"
"Sir, I saw a lot of signs that said 22, not 65."
"Oh sister, that's not the speed limit, that's the name of the highway you're on!
Oh! Silly me! Thanks for letting me know. I'll be more careful.
At this point the cop looks in the backseat where the other nuns are shaking and trembling.
Excuse me, Sister, what's wrong with your friends back there? They're shaking something terrible.
Oh, we just got off of highway 119.
