An Englishman, a Dutchman and an Irishman walk into a bar. They all order a beer. Three disgusting flies fly into each one of their beers. The Englishman pushes his beer away in disgust. The surprised Dutchman simply takes out the fly and drinks the beer. The Irishman takes out the fly, hold it over his mug and yells "Spit it out you bastard! Spit it out!"
