An Irishman, an Englishman and a Scotsman go into a pub and each order a pint
of Guinness. Just as the bartender hands them over, three flies buzz down and
land in each of the pints. The Englishman looks disgusted, pushes his pint away
and demands another pint. The Scotsman picks out the fly, shrugs, and takes a
long swallow. The Irishman reaches into the glass, pinches the fly between his
fingers and shakes him while yelling, “Spit it out, ya bastard! Spit it out!”
