Irishman, Englishman, and Scot Bar Joke

An Irishman, An Englishman and a Scot are in a bar...

...when a fly lands in each of their beers. The Englishman, disgusted, pushes the beer away and demands a new one. The Scot, picks the fly out and keeps drinking. The Irishman grabs the fly, squeezes it, and shouts, "Spit it out you little bastard!"
