The Taco Bell scene where the guy tells Stan that he will give him a 6 layer burrito was in the commercial for the original airing but, in the commercial instead of 6 layer burrito he said 5 layer burrito which Taco Bell does make.
(he said that they don't make a 5 layer burrito in the commercial)
Sharon: It's gorgeous, Dad, thank you. Oh, and tomorrow is picture day at school. Stan could wear it for his photos.
Stan's grandpa: Oh, that's wonderful. That will make me feel really good. Who's Stan?
