Flies

One day an Englishman, a Scotsman, and an Irishman walked into a pub together.

They each bought a pint of Guinness. Just as they were about to enjoy their creamy beverage, three flies landed in each of their pints, and were stuck in the thick head.

The Englishman pushed his beer away in disgust.

The Scotsman fished the fly out of his beer, and continued drinking it, as if nothing had happened.

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