On top of that, there's a scene of genuine pathos where Joe gets thrown out of the house for something that wasn't his fault. The looks of dejection and rejection on his face and in his body language tug at your heartstrings. I've seen all 190 of the stooge shorts and can't remember a similar moment.
But my favorite moment is when he's with the two alien females. Many Joe shorts have risqué and suggestive elements not seen in the Curly and Shemp shorts. Joe is giving the girls the once-over (twice-over?) and says, "Say, do you mind if I take a picture of your... spaceship?" Just before he says "spaceship," his eyes alight onto--and then immediately leave--their impressive bosoms.
I also love the moment when he's picking up his camping gear and then has it all fall out of his bag as he leaves. And lest we not forget the flick has a fair quota of stooge stomach banging, head-knocking, and dumb stuff like Larry pulling a tarp full of cans on top of his head and Moe trying to light his cigar but lighting his nose instead.
All in all, an overlooked short that leaves one satisfied.
