An Englishman, a Scotsman, and an Irishman walk into a pub.
They proceed to each buy a pint of Guinness. Just as they were about to enjoy their creamy beverage a fly landed in each of their pints and became stuck in the thick head.
The Englishman pushed his beer away from him in disgust.
The Irishman fished the offending fly out of his beer and continued drinking it as if nothing had happened. The Scotsman too, picked the fly out of his drink, held it out over the beer and then started yelling: "SPIT IT OUT, SPIT IT OUT YOU BASTARD!!!"
