The man was in no shape to drive, so he wisely left his car parked and walked home. As he was walking unsteadily along, he was stopped by a policeman. "What are you doing out here at 2:00 a.m.?" asked the officer. "I'm going to a lecture," the man said. "And who is going to give a lecture at this hour?" the cop asked. "My wife," said the man. "She will be wanting her car back that I left on the side of the road."
