THX
The Simpsons Movie: The DVD and Blu-ray releases have an unauthorized parody of the THX Tex trailers as an Easter egg, where Homer Simpson becomes annoyed by a "Tex" caricature and eventually smashes it. A disclaimer after the trailer explains that neither the trailer nor The Simpsons Movie itself involved THX's input. Because of this, an imitation of the "Deep Note" sound is used and the logo used in the parody reads "TH\".
