An Englishman, Scotsman and the Irishman sit down together at a pub and each orders, 1 pint of Guinness.
Three flies, one each into each glass lands.
The Englishman in disgust pushes his glass away.
Scotsman picks out the fly and throws away and takes a chug.
The Irishman grabs a fly and shakes him demanding “spit it you lout.“
