You may not know this but there is a hidden code hidden in all of the Pixar movies. Don’t worry it’s not some sinister encrypted message from some secret society, but more of an inside joke.

The code in question is A113 (sometimes it can be A-113 or A1-13) and is an Easter egg that appears in mostly animated movies which have been created by alumni of California Institute of the Arts, and refers to the classroom which is used by graphic design and character animation students in their first year. Some of those students include Pixar’s John Lasseter and Brad Bird.

The first appearance was on a license plate number back in the 80’s on the “Family Dog” episode of Amazing Stories which was made by Brad Bird and ever since it has appeared in other Disney movies and every Pixar movie.

Brad Bird said, “I put it into every single one of my films, including my Simpsons episodes—it’s sort of my version of Hirschfeld’s ‘Nina.'”
