We now know how Charlie Harper dies! Death by train. Charlie told TMZ that he is honored that it took something as large and violent as an oncoming train to terminate his character on Two and a Half Men. Charlie meets his end when he slips off a platform in a Paris subway station and is his by an oncoming train. Sheen said “Anything less would have been an insult.” I'm thinking something as outdated as a train is an insult, but they didn't ask me!
