Nuns on Highway 22

A cop pulls over a carload of nuns.

- Cop: Sister, this is a 65 MPH highway -- why are you going so slow?

- Sister: Sir, I saw a lot of signs that said 22, not 65.

- Cop: Oh sister, that's not the speed limit, that's the name of the highway you're on!

- Sister: 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.

- Cop: Excuse me, Sister, what's wrong with your friends back there? They're shaking something terrible.

- Sister: Oh, we just got off of highway 119.
