A-113

[Peter Paltridge]

Name a cartoon in which you have seen the mysterious "A-113" appear. (My details on what it means are foggy right now; I seem to remember that it relates to an art school.)

The Brave Little Toaster: The Master and his mother now live in Apartment A-113.

"Prehistoric Ice Man" episode of South Park: The helicopter has "A-113" written on the side.

Toy Story 2: "A-113" appears on a license plate.

That has appeared a bunch of times on The Simpsons.

Yet from what I know that number was John Lasseter's room number at Cal Arts College. Plus a bunch of people from Pixar graduated from there. Yet it's appeared in a ton of Disney movies and a bunch of times on The Simpsons. But I don't get The Simpsons connection.
