The Smiths are forced to make cutbacks because of the
economic recession. When
Roger tells
Francine that
Stan regularly spends $400 on gas for his
SUV, she threatens to replace his vehicle with a Hybrid. In an attempt to save his SUV, Stan makes a bet on a local horse at a track stadium, only to watch the horse finish the race last. Outraged, Stan confronts the
jockey, discovering that the jockey is Roger. Roger explains that he has given the horse tranquilizers to hold it back and reduce its odds. When the horse owner plans to kill the horse to prevent further monetary loss, Roger offers to buy it from him, and asks Stan for money. Stan is reluctant at first, but following Roger's promise that the horse is a guaranteed winner, he decides to buy it using his family's second mortgage. Roger tells Francine about the plan when she lectures Roger about eating too much
cream cheese. Francine is furious, but decides to trust Stan. Tired of hearing Roger reveal his actions to Francine, Stan thumps Roger's arm. In retaliation, Roger tricks Stan into giving the horse
"a full release" to boost its confidence. The horse afterwards engages in erratic behavior. The two consult a horse whisperer (after confirming he isn't Roger, who is just the secretary), who tells them that due to being molested by Stan, the horse is in a state of shock despite its body's peak physical condition, and as a result, will never race again. Roger tells Francine of this development after she glares at him for using too much
whipped cream. Using the
CIA technology once used on
Klaus in "
Finances with Wolves," Stan switches his mind with the horse's, reasoning that with its body's peak condition he can potentially win the race, over Klaus's suggestion of putting himself in a human body and getting a job doing animal noises. Before Stan and Roger head off to the stadium, Francine approaches the horse waiting in the back of the car, unaware that the horse is Stan. Saddened, she questions why her husband prioritizes his SUV over his family, leaving Stan feeling remorseful. At the venue, Stan is unable to endure the grief of disappointing Francine. So instead of heading off to the start of the race, he rushes to Francine at the spectator seats, revealing himself to her as a horse. Stan expresses his sorrow to her in regards to his selfish actions. Francine then tells him to win, giving him confidence and an encouraging attitude, and allowing him and Roger to take first place (after Roger makes himself vomit by sticking his finger down his throat to make himself lighter). Meanwhile,
Steve and his friends get employed by an old friend, Mr. Tuttle, who has over time become an obese recluse after his wife's death. Snot volunteers to retrieve Mr. Tuttle's wallet from his back pocket to receive their paycheck, but becomes trapped underneath him. Upon running to his dad for help, Steve learns from Klaus that Stan had switched his brain with the horse's. Steve uses the horse, in Stan's body, to help lift Mr. Tuttle and free Snot. Mr. Tuttle then reveals he had the money in his neck fat instead of his back pocket and tricked them into staying with him due to his loneliness. Steve then decides to reintroduce him to the neighborhood, with the horse in Stan's body pulling him. At the end of the episode, Stan in the horse's body goes to Hollywood with Roger so that the two of them can ride together with
Steven Spielberg and
his talking horse. ==Reception==
