One day an Englishman, an Irishman and a Scotsman walked into a pub together. The proceeded to each buy a pint of beer. Just as they were about to enjoy their beverage three flies landed in each of their pints.
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 Scot picked the fly out of his drink and started shaking it over the pint, yelling... "SPIT IT OUT, SPIT IT OUT YOU BASTARD!!!"
