He was walking unsteadily along

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.
