Mike "Creator of Hellboy" Mignola's The Amazing Screw-On Head was a bizarre little one-shot comic that was weird, even for him. It told the story of Screw-On Head, a robotic secret agent with interchangable bodies working for Abraham Lincoln, and his battle versus the evil Emperor Zombie.
It was awesome.
The Sci-Fi Channel recently made an equally weird half-hour animated special out of it, with the potential for a series, I think. It is possibly even more awesome, thanks to Paul Giamatti and David Hyde Pierce lending their vocal talents to Screw-On Head and Emperor Zombie, respectively.
