John Ratzenberger

John Deszo Ratzenberger (b. 1947) is an American actor, voice actor, and entrepreneur who is best known for his role as Cliff Clavin on the NBC sitcom Cheers. He reprised this role for the specials Mickey's 60th Birthday and Disneyland's 35th Anniversary Celebration. He has also voiced many characters in all the Pixar features, with at least one performance on a Disney live-action film.

The running gag of 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 movies, and he thinks that whoever did the voice of Hamm, P.T. Flea, and the Yeti (all in car form) were great actors until he realized it was the same voice actor in all those movies and asks, "What kind of a cut-rate production is this?"

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