This assumes that the green guy would fly right down and save the guy who went parasailing with a duvet. I don't know enough about DC to know whether the green guy is a good guy who's having a minor disagreement with Superman, or is one of those guys who thinks "hey, I should make the all-powerful alien uber-being aware of my existence and schemes; that'll improve my chances of getting away with my plots and plans." He packs one hell of a punch, though.
EXTRA! The private life of Clark Kent!
Isn't that called "being Superman"?
