Charlie Sheen was a Hollywood baby who rode his Daddy's coattails, made mostly bad movies, and porked a lot.
Arnold was the son of a police officer in post WWII Austria. He decided when he was 14 he would be a movie star and he would accomplish it through bodybuilding. He worked his ass off in the gym, learned English, moved to the US, brought bodybuilding into the public eye, became the greatest bodybuilder of all time, became the highest grossing actor of the 90's (made mostly bad movies that I love), became governor of the most populated state in the union, and porked a lot.
...and you're going with Charlie? I'm gonna go with Arnold.
