A police officer pulls over a carload of nuns. The officer says: “Sister, this is a 65km/h highway, why are you going so slow?”

The nun says: “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!” the nun answers. “Silly me! Thanks for letting me know. I’ll be more careful.”

At this point the officer looks in the backseat where the other nuns are shaking and trembling.

The officer says: “Excuse me, Sister, what’s wrong with your friends back there? They’re shaking something terrible.”

“Oh, we just got off highway 140.”
