Happy St Patrick's Day: An Englishman, an Irishman, and Scottish man are drinking in a bar.
A fly lands in the Englishman's pint.
The Englishman is incensed,
and pushes his beer away and orders another.
A fly lands in the Scottish man's pint.
The Scottish man looks at the fly, shrugs, and just drinks the fly down.
A fly lands in the Irishman's pint. The Irishman is furious. He picks out the fly, and violently shakes the fly over his pint glass while screaming, "Spit it out ya wee bastard!"
