This movie sounds like a good one, if you want the rest of your days to be spent in living nightmare where your only language is your mind's constant screaming. The summary for Human Centipede: First Sequence:
Internationally respected Siamese twin surgeon Dr. Josef Heiter has a demented vision for mankind’s future existence. He wants to remove human beings’ kneecaps so they have to exist on all fours and then surgically graft them mouth-to-anus to form a centipede chain. When two stranded female Americans arrive at his luxury home-cum-hospital looking for help, his long-gestating plan swiftly moves into chilling action with a shocking force. Kidnapping a third Japanese male tourist, he begins the tissue matches, teeth removal, and buttock moulding to create his triplet creature…
I suppose it's a "demented vision for mankind's future existence" if you look at it one way, but what if this Dr. Heitner has knowledge of an upcoming giant actual centipede attack? Then we'd probably thank him for giving us a suitable gladiator to compete against this insect threat.
