In the short No Dough Boys, Curly is getting throttled by the head Nazi at one point. Moe comes diving onto said Nazi's back and makes it clear no one messes with his little brother. Well, except forhim,of course.
Some people may dislike Shemp and see him as a Replacement Scrappy, but Shemp had a very successful solo career (He was the star of his own shorts series and was a popular character player in movies featuring anyone from Abbott and Costello to John Wayne). After Curly's stroke, Shemp essentially gave up his own career to step in and make sure his brother and close friend weren't dropped by Columbia Studios after Harry Cohn (a notorious miser) told Moe "I ain't paying for Two Stooges". Shemp stepping in essentially saved the act and Moe and Larry's careers.
In Back To The Woods, the Stooges are pilgrims trying to hunt on native land. When a group of braves attack them, Curly takes out several with a truly astonishing eye poke/kangaroo kick/body splash combo. Acrofatic doesn't do it justice. Later on, Larry is kidnapped and about to be scalped, and Moe and Curly disguise themselves and join the native dance - with wooden clubs hidden behind their backs. In a matter of seconds they've knocked the whole group unconscious. Curly accidentally clobbers Moe as well, but that's to be expected.
In The Sitter Downers, the Stooges are trying to build a house themselves, with the predictable chaos occurring. Moe is, of course, being his usual abusive self. At one point, his finger gets stuck in some plumbing. Larry asks to make sure that Moe really is stuck - and then begins wailing on him with a two-by-four. Sure, the beatdown lasts for only a minute and Moe soon gets free, but seeing agreeable, easy-going Larry getting a small amount of revenge is still a delight to see.
In Calling All Curs, after (somehow) managing to crawl though the intercom simply to hit Curly, Moe ends up getting stuck with only his face poking out. What does Curly do when learns this information? He plays the "She Loves Me..." game while gleefully plucking Moe's eyebrows one by one! It also serves as a Crowning Moment of Funny.
Here's another Curly example, from ''I'll Never Heil Again."
Moe Hailstone: I vanquished them! I am the winner, the world belongs to me! (to Curly, who's holding a globe) Give it to me!
Curly Herring: No, it's mine!
Moe Hailstone: Gimme that world, Herring, or I'll marinate you. LET MEHAVE IT!!
Shemp even manages to get one on Moe in "Heavenly Daze." When he's a ghost trying to get the other Stooges to redeem themselves and catches Moe being his usualself around Larry, he slaps Moe in the face! And then when he blames Larry for that and is about to "moider" him, Shemp manages to save Larry and Moe ends up hitting his hand on the wall. Heck, Shemp's own speech to Moe is awesome as well. note Too bad the jerk never got to hear it.
Shemp once got sweet revenge on not just Moe, but Larry as well in the short Husbands Beware. He found out they lied about his uncle dying and leaving him half a million dollars but only if he gets married to a ugly woman, just to get back at him for hooking them up with his mean-spirited sisters. Shemp does not take it well.
Shemp: Why you no-good, double crossing rats! (Takes out a gun and shoots them both in the rear.)
