An Irishman, an Englishman and aScotsman go into a pub and each order a pint of Guinness. Just as the bartender handsthem over, three flies buzz down and land in each of the pints. The Englishman looksdisgusted, pushes his pint away and demands another pint.  The Scotsman picks outthe 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, yabastard! Spit it out!"
