1. There is a general buzz in the air that the prefect line was the right answer in the "why do we have avatar" post. I'll throw this out there...perfection is a state of not getting better. For instance, when a business says they have a perfect safety record, it tells me that they are measuring the wrong things. When you hit that road block of perfection, you need to change what you measure. To change, you need to think outside the box of perfection you are trapped in. The key for avatar to think outside of the box is emotions, which they have abandoned long ago.
In the avatar world, there are perfect processes that have been ongoing for a millennium or more. The avatars need our help to fix those processes, because they are still trapped in the box of perfection.

To be fair, he does find things funny. He cracks up when he hears folks say, "Jesus Christ on a bicycle." Why? In his words, "It's funny, because it could not have happened."
