Plot
After his obesity embarrasses Bart at a church picnic, Homer attempts to lose weight by going on midnight jogs around town. He soon discovers "Power Sauce", an energy bar made with apples which he starts to eat regularly.
At a gym, Homer meets Rainier Wolfcastle, who becomes his fitness coach. In two months, Homer is healthier, and more muscular and reveals his new exercise habits to his family. At the gym, two Power Sauce representatives, Brad and Neil, ask Rainier to climb to the top of Springfield's tallest mountain, "The Murderhorn", as a publicity stunt. When he refuses, Bart insists Homer volunteer to do it.
Grampa begs Homer not to climb the mountain, telling him how he "died" when he was betrayed by a friend, C. W. McAllister, during their climb on the Murderhorn in 1928, also as a corporate publicity stunt. Despite this, he accepts the challenge and is aided by two Sherpas, whom he fires after waking up one night to find them secretly dragging him up. Homer radios this to Brad and Neil, who fail to convince him to abandon the climb.
