Since 1995, actor John Ratzenberger, who famously stars in the television show "Cheers" (1982–93), has voiced a character in each Pixar feature film, except "Soul" (2020) in which he had a non-speaking background character animated in his likeness instead. Pixar paid tribute to its "good luck charm" in the end credits of "Cars" (2006) by parodying scenes from three of its earlier films ("Toy Story", "Monsters, Inc.", and "A Bug's Life"), replacing all of the characters with motor vehicle versions of them. After the third scene, Mack (his character in "Cars") realizes that the same actor has been voicing characters in every film.
