Olives

A man walked into a bar and ordered martini after martini, each time removing the olives and placing them in a jar.

When the jar was filled with olives and all the drinks consumed, the man started to leave.

"Excuse me, sir," said a customer, who was puzzled over what the man had done, "What was that all about?"

"Oh," said the man, "my wife just sent me out for a jar of olives."
