After his obesity embarrasses Bart at a church picnic, Homer attempts to lose weight, and begins going on midnight jogs around town. He soon discovers Power Sauce, an energy bar made out of 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, more muscular, and reveals what he has been doing to his family. At the gym, two Power Sauce representatives ask Rainier to climb to the top of Springfield's tallest mountain, "The Murderhorn", as a publicity stunt. When he refuses, Bart insists Homer do it. Despite Grampa telling him about how he was betrayed by a friend, C. W. McAllister, during their climb on the Murderhorn, Homer accepts and is aided by two Sherpas, but fires them after waking up one night to find them secretly dragging him up. Once the Power Sauce representatives get wind of the situation, they unsuccessfully attempt to warn Homer not to continue with the dangerous stunt, revealing that the bar is actually made up of apple cores and Chinese newspapers. The mountain proves too treacherous and high for Homer, who takes shelter in a cave. In it, he finds McAllister's frozen body and evidence proving it was Grampa who betrayed him. Too tired and ashamed to continue, Homer sticks his flag pole on the ledge, ripping off the Power Sauce flag and tying his own make-shift white flag to the pole. The ensuing crack collapses the rest of the mountain, making where he is on now the peak. Proud, he uses McAllister's body to sled down, where he is greeted by the crowd. When he goes to show the family, they find out that the flag has disappeared from the pole. Nevetheless, Bart is proud of his father for making it to the top of the mountain.
Production
The episode was pitched and written by John Swartzwelder. The writing staff had to find a new angle for Homer's weight problems, as the idea had been used several times before. This was emphasized in this episode when Marge does not seem to care that Homer is going to try to lose weight again. In the scenes where the Sherpas were speaking, the show staff went to great lengths to find translations. Originally, the producers of the film adaption of the book Into Thin Air were contacted to help. The film producers were shocked at the trouble the Simpsons staff were going to, and replied that they had simply made up translations in the film. The staff then had to consult various experts by telephone. The idea of the upper part of the mountain collapsing so Homer would be at the peak came from Mike Scully's brother Brian, after the staff "desperately needed a way out".
Cultural references
The mountain Homer must climb, the Murderhorn, is a reference to the mountain Matterhorn, which is located in the Swiss Alps. The name of the episode is a reference to the Fox series King of The Hill.
Reception
In its original broadcast, "King of the Hill" finished 23rd in ratings for the week of April 27–May 4, 1998, with a Nielsen rating of 9.4, equivalent to approximately 9.2 million viewing households. It was the fourth highest-rated show on the Fox network that week, following The X-Files, King of the Hill, and Ally McBeal. The authors of the book I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide, Warren Martyn and Adrian Wood, thought well of the episode, stating: "A quite charming little adventure in which, in an effort to impress Bart, Homer undertakes a dangerous adventure and comes through successfully. It's nice because just for once, to all intents and purposes, Homer actually succeeds in something."
