A state trooper noticed a car puttering along at 22 mph. So he turned on his lights and pulled the driver over. Approaching the car, he noticed that five old ladies were inside, and they looked wide-eyed and terribly pale.
The driver pleaded with him, "Officer, I don't understand, I was driving according to the speed limit! What seems to be the problem?"
"Ma'am," the officer replies, "You weren't speeding, but driving slower than the speed limit can also be dangerous."
"I beg to differ, sir, I was following the speed limit exactly: 22 miles an hour!" the old woman said.
The state police officer, chuckling, explained to her that "22" was the route number, not the speed limit. A bit embarrassed, the woman grinned and thanked the officer for pointing out her error.
"But before I let you go, ma'am, I have to ask: Is everyone in this car okay? These women seem awfully shaken," the officer asked.
"Oh, they'll be all right in a minute officer. We just got off Route 119."
