In Toy Story, Sid’s sister Hannah dresses Buzz up for a tea party and calls him Mrs. Nesbit. The teapot she uses is a Utah teapot or Newell teapot, a famous 3D computer model which has become a standard reference object (and something of an in-joke) in the computer graphics community. The teapot model was created in 1975 by early computer graphics researcher Martin Newell, a member of the pioneering graphics program at the University of Utah.
