An English man, an Irish man and a Scots man were sitting at the bar. Each had ordered a pint of Guinness. Into each pint dropped a fly. The English man pushed away the glass in disgust and wouldn't drink at all. The Scot picks the fly out, tosses it aside and proceeds to drink. The Irish man lifts the fly out by its wings, holds it over the glass and shakes it, saying "spit it out, ya bastard! Spit it out!"
