Son! Yeah dad? How's your day pal? Great dad, how's yours? Super! Say son, how'd you like to go fishing this weekend?! Great, dad! But I've got homework to do. That's all right son, you can do it on the boat! Gee! Dear, isn't our son swell? Yes dear, isn't life swell?

Extermination of My Filthy Species by Skinless
On the afternoon of August 18, 1973, five young people in a Volkswagen van ran out of gas on a farm road in South Texas. Four of them were never seen again. The next morning the one survivor, Sally Hardesty-Enright, was picked up on a roadside. Blood-caked and screaming murder.
Sally said she had broken out of a window in Hell. The girl babbled a mad tale: a cannibal family in an isolated farmhouse...chain-sawed fingers and bones...her brother, her friends hacked up for barbeque...chairs made of human skeletons...Then she sank into catatonia. Texas lawmen mounted a month-long manhunt, but could not locate the macabre farmhouse. They could find no killers and no victims. No facts; no crime. Officially, on the records, The Texas Chainsaw Massacre never happened. But during the last 13 years, over and over again reports of bizarre, grisly chainsaw mass murders have persisted all across the state of Texas. The Texas Chainsaw Massacre has not stopped. It haunts Texas. It seems to have no end.
