An Englishman, an Irishman and a Scotsman 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 Scotsman’s pint. The Scotsman 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, you wee bastard!”
