One night a man – who was in no shape to drive – wisely left his car parked and walked home. As he was walking unsteadily along the road, 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 just who is going to give a lecture at this hour?” the cop asked.

“My wife.” said the man.
