While Homer is visiting Moe's one day, Carl and Lenny confess that when they were still in high school with Homer, their now-retired prinicpal ordered them to bury the ballot box for their class presidental election (in which Homer ran against Vance Connor -- who had recently beeen inducted to the Springfield Wall of Fame -- and lost). He excavates the box and discovers that he had the most votes. He visits the principal, who confessed that he burried the ballot box to protect Homer from the ridicule that would have resulted had he won. As the Simpsons dine at Luigi's Restaurant that night, Homer meets the saucier of the restaurant, who uses his special tomato sauce to give him a vision what what his life would be like if he became the class president.
This episode is the first one to be shown in high definition and the first episode since season two's "Bart Gets an F" to have a new opening sequence.
* TheCheerleader: Debbie Pinson
* ForWantOfANail: In the timeline where Homer won the election, he took Debbie Pinson to the prom, Mr. Burns would have give him a better position at the plant, he'd have a bigger house built next to the one where Mainstream Homer lives and use the mainstream one as a guest house where Abe lives and doesn't complain about anything, and he used protection to avoid having children. And he still has hair.
