A113

A113 (pronounced A1-13) was the classroom number used by character animation students at the California Institute of the Arts. Many of its alumni (including Pixar staff) have used the number in their professional works. It is said to appear in some way, shape, or form in every Pixar film. This running gag has also appeared in other Disney-distributed films, such as The Brave Little Toaster, Lilo & Stitch, and The Avengers, as well as some non-Disney films, such as Rise of the Planet of the Apes, Mission Impossible: Ghost Protocol, etc.
