Of particular note is the animations at the end of the video. The /welcome animation is a worgen pointing, waving, and then getting down on all fours to sniff the air in-front of him; as if to smell the nether regions of the person being greeted as canines are prone to do. There is some discussion if this it worgen idle animation at the wrong time, or if this is part of the overall /welcome animation sequence.
Unforunately we don't know, but we're all having a good laugh over it. And now you can do.
The goods after the break, while it still exists.
Note that there is an annotation in the video that says the video is from BlizzCon 2009 -- however that's incorrect.
