Santa’s Little Helper
Nitpicky? Sure. But that’s what a good list is all about. In the pilot episode entitled “Simpsons Roasting on an Open Fire,” we are introduced to the Simpsons’ beloved dog, Santa’s Little Helper. However, in the later episode “Homer’s Barbershop Quartet” (which is a flashback episode), we see Santa’s Little Helper burying something in the backyard. This was long before they ever owned him.
