The Simpsons would, in a later episode "The Simpsons Spin-Off Showcase," mock the addition of The Great Gazoo into some of the final episodes of The Flintstones by stating that, in future episodes, Homer would meet a green space alien named Ozmodiar that only he can see. Commercialism Television advertisements are also parodied. As an example there is a song and visual sequence in the episode "The Last Temptation of Krust" that was modeled after Ford commercials. The sequence is a parody of a commercial for a sport utility vehicle, and Hank Williams Jr. sings a song about the fictional "Canyonero" accompanied by country guitar music and whip cracks. The song "Canyonero" closely resembles the theme to the 1960s television series Rawhide. The first verse of the song is: "Can you name the car with a four-wheel drive / Smells like a steak and seats thirty-five? / Canyonero! / Canyonero!" Turner wrote positively of the Canyonero spoof piece in Planet Simpson, calling it "a brilliant parody of an SUV ad". In an article in the journal Environmental Politics Steve Vanderheiden commented that the Canyonero reflected an "anti-SUV" stance by The Simpsons. In an article in the San Francisco Chronicle about SUV owners, Vicki Haddock wrote "SUV owners have become something of a punch line, succinctly captured in a "Simpsons" parody touting the apocryphal Canyonero [...]" In his book Watching with The Simpsons: Television, Parody, and Intertextuality, Jonathan Gray analyses a scene from the episode "Girly Edition" in which it is announced that Kidz News has been replaced by the children's cartoon The Mattel and Mars Bar Quick Energy Chocobot Hour (a reference to the Mattel toys and the Mars chocolate bar). He says this mocks "how many children's programs have become little more than the ad to the merchandise". Gray also writes that The Simpsons "illustrates how the ad as genre has itself already invaded many, if not all, genres. Ads and marketing do not limit themselves to the space between programs; rather, they are themselves textual invaders, and part of The Simpsons parodic attack on ads involves revealing their hiding places in other texts." AnimationThe Itchy & Scratchy Show is a show within a show that appears occasionally in episodes of The Simpsons. They typically appear in the form of 15-60 second cartoons that are filled with over-the-top violence, usually initiated by Itchy the mouse against Scratchy the cat;
