John Deszo Ratzenberger is an American actor, voice actor, director, producer, screenwriter, and entrepreneur, who is best known for his role as Cliff Clavin in Cheers. He reprised this role for Mickey's 60th Birthday and Disneyland's 35th Anniversary Celebration. He also has done voice work in every Pixar film (except for Soul, Luca, and Turning Red), with at least one performance on a Disney live-action television film.

The running gag of John Ratzenberger portraying at least one character in every Pixar movie is referenced during the end credits of Cars; when Mack watches the Cars-parodies of previous Pixar films and he thinks that whoever did the voice of Hamm, Yeti, and P.T. Flea (all in car form) were great actors until he realized it was the same voice actor in all those films and asks, "What kind of a cut-rate production is this?".

P.T. Flea from A Bug's Life is John Ratzenberger's personal favorite character of his Pixar roles.

While Soul is one of three Pixar films (the others being Luca and Turning Red) in which John Ratzenberger doesn't have a voice role, his likeness does appear in the film.
