One perfect moment DCAU Luthor
Superman Adventures #41 was unsual inasmuch as it featured 22 one-page stories rather than one 22 page story.
This is one of my favourites.
It's safe to say that I never once imagined I'd be reading Luthor and Mercy dialogue and expecting a "Narf!" or "Zort!", but it works rather well, no? :)
And if anyone would care to post the Alan Moore Swamp Thing sequence where Luthor is hired for ten minutes by a consortium of bad guys who want Swamp Thing out of the way, and devises a method in nine and a half minutes, because he wanted to be sure to leave them enough time to sign the cheque for his fee, that would be an awesome moment too! :)
