Cartoonist Michael Kupperman is, as we all know one of the world’s funniest humans. Tales Designed to Thrizzle proves that. He’s also obsessed with Mark Twain, something also proved by Thrizzle. And now, he’s made a cartoon about Twain’s wacky adventures aboard a raft made of garbage, now available on Adult Swim. If you poke around on his Tumblr, you’ll also see some pretty hilarious outtakes of things that he couldn’t animate in the basic style used. Warning: Contains pants dropping.
