After embarrassing Bart during a game of Capture the Flag at a church picnic, Homer decides to get in shape (despite everyone else saying that Homer can't commit to a diet and exercise regimen), and his newly-sculpted muscles from an energy bar and exercise makes him the perfect candidate for a publicity stunt.

* CommieNazis: The TropeNamer in a [=McBain=] movie.
%%* DietEpisode
* DirtyCoward: After it was revealed that Grampa betrayed his partner (not the other way around), he chose to flee rather than explain himself.
* DudeNotFunny: InUniverse, while watching the [=McBain=] movie, Marge says [[BondOneLiner "Now that's what I call breakneck speed!"]] and laughs, but Bart stares at her and flatly says "Mom, a man just died.". Marge groans in annoyance. Bart probably just said that cause her joke wasn't funny.
* FakeUltimateHero: Homer realizes that he's becoming this when he learns the Sherpas were taking him up the mountain while he was sleeping.
** Grampa Simpson claimed to have been betrayed by his own partner: Grampa himself stole the last oxygen tank, and abandoned him, but not before taking a bite out of him.
* HonorBeforeReason: When Homer sends the Sherpas home, he tells Brad and Neil he's going on alone, making them urge Homer to go back himself, but Homer insists he'll carry on, because he'd promised Bart he'd do it. [[SubvertedTrope When one of the Sherpas says Homer should go back down and start it all over for the promise's sake, Homer ignores the comment.]]
* IDontLikeTheSoundOfThatPlace: Mount Murderhorn.
* IfIDoNotReturn: The dead climber has such a line in his journal.
* ImAHumanitarian: Grampa tried eating his partner.
* MagicFeather: Powersauce bars, the source of Homer's confidence, turn out to be made of [[spoiler: apple cores and Chinese newspapers.]]
* NotThisOneThatOne: When Homer is told he has to climb Mount Murderhorn, he's pointed towards a massive mountain outside Springfield. Homer gasps in shock, but Neil informs him that it's actually a much bigger mountain next to it.
* PeekABooCorpse: When Homer turns on his lamp in the cave, he shudders seeing the corpse.
* RevealShot: At least twice. When Homer mistakes a small mountain for Mount Murderhorn, [[OverlyLongGag two reveal shots are used]] to show the real mountain. Another reveal shot when Homer uses the oxygen bottles and the camera zooms out to show he hasn't come that far.
* SweetAndSourGrapes: When he realizes his father let him down, Homer thinks he's let Bart down himself, so he decides to give up on climbing the mountain. Taking the flag out, he takes the Powersauce banner off and puts a sheet marked "Simpson" on it, saying "It's not the top, but it's as close as a Simpson's gonna get.", and hammers it in, but it causes a landslide bringing down the top of the mountain, thereby making where he's standing the top.
