I Have To Admit, I'd Probably Buy "Watchmen Babies"

Here's Alan Moore (along with Art Spiegelman, and Dan Clowes) on The Simpsons:



If anyone could write an interesting story about a non-radioactive, heroin-addicted jazz critic, it'd be Alan.
It was an all-around good episode from a comic book geek perspective, even apart from the appearances by Alan and the others. Lots of geeky references.
This episode marked the second time in one day that Alan made me laugh, with the first being with this passage from The Black Dossier in a segment detailing the life of a transgendered immortal:

Male once more, I returned to Rome in 70 BC, my fling with its founders now forgotten. Embroiled in slave revolts, I escaped punishment by simply declaring "I'm Vito," everyone else apparently being named "Spartacus."

Fellow author and friend of Alan Neil Gaiman was offered the opportunity to also appear on an episode of The Simpsons by creator Matt Groening. Neil declined, stating that he'd much rather appear as a head in a jar on Futurama. Groening, who is bringing Futurama back for a series of direct-to-DVD movies (which will air as episodes on Comedy Central) told him, "That can be arranged."
