Okay, so I already linked to these on io9, but I can't help it, I just love Randy Milholland's "The Last Trick-Or-Treaters" comics. Yes, it's all about killing small children, but the way Milholland riffs on it, it's terribly funny. Plus, I particularly enjoy the way he uses his running watercolors to complement the gore.
