Hmmm. Cant really blame the guy. If your wife looked like a cross between Rosanne and a lesbian hippopotamus... you'd probably explore other options too.
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.
