Three men walk into a bar: a Greek, an Italian and an Irishman. Each man orders a beer. Three flys fly into the tavern and one fly lands in each man's drink.
The Italian man pulls the fly out of his beer, says "tutto 'e bene" (all is well)" and drinks the beer down.
The Greek man shows his beer with the fly still inside to the barman and asks for another beer.
The Irishman grabs the fly out of the beer, takes it by it's wings, while yelling
"Cough it up, you wee theivin' bastard!"
