Murphy walked into a bar and ordered a Martini, followed by another Martini. After each Martini, Murphy would remove the olives and place them in a jar.
He kept this up for over an hour, by which time he was rather sozzled as you might imagine and Patrick, the bartender was rather puzzled.
When the jar was filled with olives and all the drinks consumed, Murphy payed the bartender and started to leave.
“S’cuse me”, said Patrick, who had been watching what Murphy had done and was totally intrigued by it, “what was that all about? You usually come in here and drink Guinness, so what’s with all the Martinis and what’s with the olives in the jar too?”
“Nothin’, said Murphy, “my wife just sent me out for a jar of olives!”
