Actually it was James Dean who first said it. The orginal quote was, "Live fast, die young, and leave a beautiful corpse." Sounds like ol Jimmy wasn't afraid to embrace his feminine side. ;)

“Live fast, die young and have a good-looking corpse”,

The first quote has been slightly rearranged over the years. It comes from a 1949 movie called Knock on Any Door, starring Humphrey Bogart as a liberal-minded lawyer trying to save a young hoodlum accused of murder. The hoodlum, Pretty Boy Romano, was played by John Derek who was, indeed, one of the best- looking actors who ever stood before a camera. The exact phrase, as he said it in the movie, was: “I wanna live fast, die young and leave a beautiful corpse.”

I am watching a VHS copy of "Knock On Any Door" as I write this. The exact phrase spoken by John Derek was not as quoted above. The correct lines, by "Nick Romano" to his barber (played by Chester Conklin) are as follows: "If it's in my blood, who cares? Live fast, die young, have a good looking corpse."
