Benito Pacifico and Vincent Scott are quarreling brothers Joe and Rico, living in squalor with little ambition to do better in life.
Hoping to change that, their domineering mother ships them off to Stranger City, hoping they’ll learn a thing or two from their brother Mike (Gordon Mitchell).
After all, he owns a successful saloon there where he’s surrounded by lovely young women.
Mike introduces his brothers to saloon girls Dolores (Malisa Longo) and Jeanine (Dada Gallotti).
The boys are bashful at first; they’ve never been with a girl before.
But, before you know it, they’ve fallen in love, though it’s the bartender’s young daughter who’s smitten Rico.
Meanwhile, their parents show up in town, just in time to see Mike risk everything he owns in a high-stakes poker game.

If you’re looking for an insipid comedy Western that will have you wondering why you bothered as the credits rolled … well, you’ve found it.
This film matches the likes of Tedeum (1972), The Magnificent West (1972) and An Animal Called Man (1973) when it comes to Spaghetti comedies you’d be better off avoiding.
In order to spare you the trouble of watching, I’ll spoil the twist.
The father of Joe and Rico is a half-wit to the point where he has to be tied to the back of the wagon when ma rolls into Stranger City.
Once Mike has lost everything he owns in that card game, his ma beats him with a rolling pin until he’s knocked unconscious.
The film’s ending features both pa and Mike happily eating from straw-like devices. Now they’re matching simpletons. Oh, boy.
There’s a scene in which Joe and Rico manage to eat a meal while riding a donkey. And another in which six blind-folded combatants duke it out in a barroom brawl, with $500 going to the last man standing. That’s as clever as this one gets.

The Crucified Girls of San Ramon is not an alternative title for this western, is a different movie set a convent.
I believe someone has updated the IMDb file for this movie, and some cast and characters have been changed. Check it, as well the Italian site Davinotti.
Thanks!
