This is from the 1976 classic Water Power. It's a lot like Taxi Driver, except this Travis Bickle has a little fetish for forcing woman into doing enemas at gun point. The film is actually based on real crimes committed by an Illinois man dubbed the "Enema Bandit". Anyway he's dead now, so R.I.P you scat-loving motherfucker.
Nothing says revenge like like mixing bodily fluids into the foods of others. Think about how much spit, piss, shit and semen you've unwittingly ingested at the hands of motherfuckers like this. Processed food 4 life.
Vintage porno with family undertones makes me laugh. It also heightens my urge to be transported back to the 70's so that I can fuck the shit out of hippies along side mothers with beehive hairdos.
