I picked Clark. Why? Because he is the real person, and Superman the facade. Clark has real worries, a real job, ideals, a LIFE. Look how boring he thought his life would be in TOGOM when he thought he'd have to be Superman only for the rest of his life. So I'd like the person, please. That way, even if Supes disappeared, Clark would remain.

Time is too slow for those who wait, too swift for those who fear, too long for those who grieve, too short for those who rejoice, but for those who love - time is eternity --Henry van Dyke
