I liked it when some villain was saying that Clark the Bumbling fool is exactly what he really thinking of Humanity, that it's not a disguise but an attempt to blend in with the rest of the bumbling fools.
I remember Bill in Kill Bill Vol II expousing this theory and it kinda rocked my world view for a milliseconf=d because what he was saying did seem to make sense. Other heroes tended to don a costume - spiderman, Batman - but Superman's costume in a way was Clark Kent because the big S came with Clark in his ship from Krypton.
