What on Earth!
The Canadian Film board use to sponsor some great animation, Including a whimsical mocumentary told by martians as they observe our planet. The animated short What on Earth! is a fantastic look. I'll let the description from the Canadian NFB speak for itself:
This film shows what many Earthlings have long feared (and what Martians might logically deem to be the case)--that the automobile has inherited the Earth. An animated film, it shows life on Earth as one long, unending conga-line of cars. The Martian visitors judge them to be the true inhabitants of Earth, while we seem to be parasites infesting the autos.
