Well, not exactly, but Tom, from Tom vs The Flash started out as Tom vs The JLA and did podcasts of JLA 198 & 199 that starred Jonah Hex (and which I covered here & here. Tom's reviews/recaps are about 10 minutes and are as addictive as cashews (for folks with nut allergies, substitute the words "Tax Free Cash").
He is fast, furious, and funny as hell. I may write in and ask him to review Jonah Hex #73, that would be a hoot and a half. Until then I'm tossing Tom onto my blogroll.
