An Englishman, American, and an Irishman were sat atop a skyscraper after a days heavy drinking..
They had drunk many pints.. and the American turned to the Irishman and said 'After 10 pints it's possible to jump off this building and fly for several seconds'
The Irishman looked unimpressed..'That's impossible' he said.
So the American finished his pint, and proceeded to jump off the building, flying around an opposite tower before returning to the skyscraper with his mates..
'See' he said.. 'It's easy'
The Irishman was exstatic.. 'Here I go he said'
He jumped off the building.. and plummeted to his death..
The Englishman turned to the American and said..
'Fuckin hell superman.. you're a right bastard when ya pissed!!
