McQuillan 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 Irishman started to leave.

"S'cuse me," said a customer, who was puzzled over what McQuillan had done.
"What was that all about?"
"Nothing," said the Irishman, "my wife just sent me out for a jar of olives."
