An Engilshman, a Scotsman and an Irishman went into a pub for a pint of Guinness one day.
After being served a fly landed in each of their pints and stuck in the creamy heads.
The Englishman pushed his pint away from him in disgust and proceeded to order another pint.
The Scotsman simply fished the offending fly out with his finger and proceeded to drink his pint as if nothing had happened.
The Irishman, eyes wide with anger grabbed the fly and held it over his pint shouting "SPIT IT OUT!!! SPIT IT OUT YOU BASTARAD!!!"
