A cop's on the highway when he sees a car that's going 22 miles an hour. So he turns on his lights and pulls it over. Inside the car are four old ladies, all looking pale and trembling.
The driver manages to look up at the cop and says, "What's wrong, officer? I was doing the speed limit. I swear."
The cop says, "Actually, you were going under the speed limit. Going too slow on the highway is almost as dangerous as going too fast."
The old lady says, "But, officer, I was going twenty-two, just like the sign says."
The cop looks at the sign she's pointing at and says, "Ma'am, that sign is the route number, not the speed limit."
The old lady blushes and says, "Oh, well, that explains a few things."
"Yes. Now are you all right? You all look like you've seen a ghost."
The lady says, "Oh, we'll be fine in a minute. We just got off Route 119."
