An Englishman, a Scotsman and an Irishman
One day an Englishman, a Scotsman, and an Irishman walked into a pub together. They each proceeded to buy a pint of Guinness. Just as they where about to enjoy their creamy beverage three flys landed in each of their pints, and were stuck in the thick head.

The Englishman pushed his beer from him in disgust.

The Scotsman scooped at his beer until he washed the fly out and then continued drinking.

The Irishman carefully picked the fly out of his drink, then held it out over the beer and started yelling "SPIT IT OUT YOU -------! SPIT IT OUT!!!!"
