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.

* 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.
* WellDoneDadGuy: Homer.
