The haircut thing has always bothered me too. He must be pretty good with that heat vision. Maybe he has a kryptonite power Flowbee.
This is something that has been discussed and joked about for years, but what about simple human, ah, intimacy. Wouldn't he encounter a few problems with the relatively fragile nature of Lois and her human parts? Could Supes have to pee so bad it would go right though the urinal?
As I mentioned in another thread, the whole issue with his clothes and what he does with them is a big question. Also, does he happen to have a lot of time during the day when he can just take off (literally) from work at the Daily Planet and save people? Two 15 minute breaks and an hour lunch doesn't offer much time to save the world, does it? Does he use sick time or what?
Also, he says he doesn't have to eat, but it's something he's gotten used to. Not sure about that one...
