I'd get fat for $1mil US. Just enough to hit a sloppy 30 BMI. Then instantly cut back and lose it. Bank the after-tax cash, invest some, buy a slick new car, maybe move, and rent out a billboard shaming fats along a major thoroughfare with something like "I could do it as a joke, look who's laughing now, fatty." Edit: Read it as million, of fucking course I'd do it for a cool billion. Gods be damned. Get me hostess on the line. I'm gonna need some pizza hut, stat! This is a case for Pappa John's! Seriously though. I'd cheat the system for a billion. Ive been miserable for far less. At least this would have an expiration date or, err, weight, attached to it.
