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.
- Artistic License – Geography: A mountain more than five vertical miles high would be higher than Mt. Everest, making the Murderhorn impossible.
- Blatant Lies: The two Powersauce guys lie frequently. First of all, everything they say about their product is a sham, the supposedly healthy energy bars made of apple cores and old Chinese newspapers. Second, when Homer sends the Sherpas home and goes alone, they tell the viewers that he has switched to their competitor, Vita-Peach Health Log. (In an attempt to absolve themselves of responsibility when he doesn't survive.)
Grampa: I fell 8,000 feet onto a pile of jagged rocks. Of course, folks were tougher in those days. I was jitterbugging that very night!
- Also, the end of Grampa's story:
- Commie Nazis: The Trope Namer in a McBain movie.
- Dirty Coward: After it was revealed that Grampa betrayed his partner (not the other way around), he chose to flee rather than explain himself.
- Disproportionate Retribution: Mr. Burns is tagged "it" by Ralph. Burns retaliates by chasing Ralph in his car.Ralph: Aaah! You're not it!
- Dude, Not Funny!: In-Universe, while watching the McBain movie, Marge says "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.
- Fake Ultimate Hero: 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.
- Honor Before Reason: 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. 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.
- I Don't Like the Sound of That Place: Mount Murderhorn.
- If I Do Not Return: The dead climber has such a line in his journal.
- I'm a Humanitarian: Grampa tried eating his partner.
- Irony: Homer complains that they had a church picnic last week; Marge corrects him: "No they didn't. You just brought a bucket of chicken to church." Homer replies, "If God didn't want us to eat in church, He would've made gluttony a sin." Which it is.
- It Is Pronounced Tro-PAY: When Homer first comes across the gym, he asks, "Gyme? What's a gyme? (opens the door and sees people working out) Ohhhh, a gyme."
- Magic Feather: Powersauce bars, the source of Homer's confidence, turn out to be made of apple cores and Chinese newspapers.
- Major Injury Underreaction: After Homer compresses five pounds of spaghetti into one bar and eats it, he calmly picks up the phone and says, "Hospital, please."
- Not This One, That One: 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.
- Peek-A-Boo Corpse: When Homer turns on his lamp in the cave, he shudders seeing the corpse.
- Reveal Shot: At least twice. When Homer mistakes a small mountain for Mount Murderhorn, 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.
- Sweet and Sour Grapes: 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.
- Tempting Fate: After working out for weeks, Homer coaxes the family to try and find some flab on his body. Bart and Lisa immediately grab some, causing Homer to tell them to feel his biceps, which is the only part that isn't flabby anymore.
