The door of Room A113 c. 2005

A113 (sometimes A-113, A-1-13, A1-13 or A11-3) is an inside joke and Easter egg in media developed by alumni of California Institute of the Arts, referring to the classroom used by graphic design and character animation students.[citation needed]


Students who have used the classroom include John Lasseter, Tim Burton, Michael Peraza, and Brad Bird. It has appeared in other Disney movies and almost every Pixar movie.[citation needed]

Brad Bird first used it for a license plate number in the "Family Dog" episode of Amazing Stories: "I put it into every single one of my films, including my Simpsons episodes—it's sort of my version of caricaturist Al Hirschfeld's 'Nina'."[1] It appears in South Park, Aqua Teen Hunger Force and the SPA Studios animated film Klaus.[2] The first Disney movie Bird used it in was The Brave Little Toaster (1987), in which he was an animator.[3] It can be seen as The Master's apartment address when Toaster and his friends knock on the door.
