Pixar and Short Animations

My favourite part of watching a new Pixar movie, is the short animation at the beginning. They are always clever, funny with great animation and usually a good moral to the story. A few years ago, I bought the Pixar DVD, which explains the beginning and subsequent success of the company. It's really interesting, and features many of their short animations. Here are my favourites:
