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."
