Did I miss something re B. Watterson? 'Cause last I checked, reclusive-artist-who-ended-his-strip-before-it-either-got-stale-or-taken-over-by-committee ≠ asshole. Unless, like, I'm going by a different definish.

Also, going back to the original tippity-topic, the most disturbing thing about this whole situash isn't even that this Rob Granola-who's-it claimed to be working on Calvin & Hobbes, but that he was apparently going to conventions and selling shit for like years (one commenter in the OP's link said 15)! I guess being retardedly brash and delusional worked for the dude, up to a point.
