Inside Out: 22 Easter Eggs, In-Jokes And References You Need To See

2. John Ratzenberger's Cameo

You literally can't have a Pixar film without John Ratzenberger. The Cheers actor started out as Hamm in Toy Story, but kept picking up supporting roles until it reached the point where he had become a major running joke. In recent movies, however, Ratzenberger's cameos have been increasingly less prominent, with Inside Out being his slightest yet; he's the brain worker who finishes off the installing of the new control console at the end of the film. Here's hoping his appearance in The Good Dinosaur is a little more involved.
