Trivia

 * Ratzenberger has been in every full-length Pixar film to date. **This is very similar to Stan Lee's cameos in the Marvel Films.
 * His favorite role is P.T. Flea from A Bug's Life.
 * The running gag in which John Ratzenberger portrays at least one character in every Pixar movie is referenced during the end credits of the movie Cars; where 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 wonders, "What kind of a cut-rate production is this?"
