When I was in college learning game development, I was learning how to 3D Model using a Software called 3DS Max, and in that software, you had access to a few shapes to use for modeling. a Cube, Sphere, Cylinder, and the strangest one... A Teapot... I never really question it, but its neet to now see a reason for the Teapot being a pre-made model in 3DS Max.
