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 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 from him in disgust.
The Scotsman fished the offending fly out of his beer and continued drinking it as if nothing had happened.
The Irishman picked the fly out of his drink, held it out over the beer and yelled "Spit it out! Spit it out, you BLOKE!"
