Homer is left with without a job and only thirteen dollars. He gets a hot tip from his his buddy, Barney Gumble, and takes Bart to the dog track. Homer bets on another dog, "Santa's Little Helper," on a hunch instead. Santa's Little Helper finishes last.
As a dejected Homer and Bart leave the track, Santa's Little Helper gets the boot from his owner for losing another race. Bart is ecstatic when Homer reluctantly agrees to take the dog home.
