Actually, as crinosg said, that's one of the things I like about him.
I seem to recall some Justice League story or another, in which Lex Luthor and his Injustice Gang are cornered by the Justice League, and one of the other bad guys basically says to Luthor, "You're the smartest guy in this room, Luthor! What do we do now?" To which Luthor replies, "That's right, I am the smartest person in this room; that's why I'm doing this," and he activates his personal teleporter.
