An American,an Irishman and an Englishman were drinking Guinness on top of the Empire State Building.The American turned to the Irishnan and said "Did you know,Paddy,that when you have drunk 15 pints of Guinness, you can actually FLY !" and with that,he jumps off the roof, flies round in a circle, and lands safely back. "Well" says Paddy."Thatchss amazing, oi musht ave a go at dat!" so off he jumps, and falls to a horrible death. The Englishman, having observed all this, walks up to the American , looks him right in the eye and says "I say, Superman, you really are a right bastard when you"ve had a drink!".
