A cop pulls over an old lady driving very slowly on the highway and sees three other old ladies in the car, all of whom are terrified.
Cop: I pulled you over because you were driving 35 miles per hour on the highway.
Old Lady: Well, that’s because the speed limit is 35.
Cop: No, this is HIGHWAY 35. The speed limit is 65. By the way, why are these other three women looking so terrified?
Old Lady: Ohhh, that’s because we just got off of highway 145.
