Going To A Lecture

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 A.M.?" said 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.
