Probly heard thos one but hear goes-
Superman was flying over New York City one day looking for trouble when all of a sudden he spotted Wonder Woman laying completely starkers on the roof of a sky scraper. Superman thought to himself "hmmm I'm feeling a bit randy and because I'm the speed of light I can fly down to her and do the naught in less than a second, she wouldn't know what hit her'. Any way he flys down and does his business in the blink of an eye and flys off. The Invisible Man jumps of Wonder Woman and shouts "WHATTHE BLOODY HELL WAS THAT MY ARSE IS KILLIN".
Hope you enjoyed it and if I've offended anyone I'm sorry
