Again, I don't really know what my favorite is, but I've picked out one to talk about.
It's actually a deleted scene from Revenge of the Sith.
|The Moons of Iego|
The rest of the clip is a great too. I love the Obi-Wan/Anakin interaction - you can see that they're such good friends, and they seem to have fun together. It's sad that their friendship falls apart soon after, but until then it's fantastic.
May the Force be with you!
