Why so Serious?... Wonder Woman & Superman

(Superman) "It doesn't matter what we do, they will always destroy each other."

(Wonder Woman) "So let's just take a step back and let them do it."

(Superman) "And there is just the two of us left?"

(Wonder Woman) "Yes."

(Superman) "So how do we kill each other?"

(Wonder Woman) "Well, maybe we don't"

(Superman) "Meaning what? We let them all die and...?"

(Wonder Woman) "I change my name to Eve and you change your name to Adam."
