Heh, that was freaking great, horny grandpa attack, thanks a lot for sharing :D
Well the one guy was obviously just a horny old man with a scheme to get some nooky, but that other group with the crazy black and white eyes attacking everything that moved must have been possessed or under the influence of those mushrooms we saw 'em picking and eating in the forest in the first part of the story........yeah, those guys were fucking great, they were some absolute rape machines, good for them :D
