Gladly.
Well, Superman basically proves to Lex that he is, in fact, pretty fast and destroys all of his plans. Then he goes to tell Batman about it.
Batman asked him what he did after catching the missles. Superman says, "Oh the usual, made sure they put Luthor away, made out with Lois for a little bit, flew out to space, smiled for the camera..." Superman also said that Luthor had kryptonite on him that would have ruined him if he would have just whipped it out. Instead he told him his entire plan and tried to trick Superman into finding it. This led Batman to decide "villains are stupid."
Batman is impressed, but goes on about how he would have stopped Luthor. Basically everything Batman would have done involved a gadget on his belt and Superman makes fun of him for it. The end dialogue is the best. It went something like this:
Batman: I'm Batman.
Superman: I know you are.
B: It's what I do.
S: I know. You say that
a lot. B: I carry things on my belt. Cause I'm Batman.
S: Dude, it's cool.
I obviously don't do it justice. Trust me, it's absolutely hilarious!
