Waiting to Have it

It was a small town and the patrolman was making his evening rounds. As he was checking a used car lot, he came upon two nuns sitting in a used car.

He stopped and asked them if they were stealing the car. They said, "Heavens no, we bought it."

He said, "Then why don't you drive it away?"

"We can't drive", they said, “We were told if we bought a car here, we'd get screwed! So we're just waiting."
