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.?" 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.
