That is some pretty incredible stuff. Not only the agility of the robot, but how it responds to challenges (the first video, obviously). Like when the guy kicks it - The robot senses the momentum shift, and kicks the legs out to stabilize itself. Or when it does that stutter step on the ice (1:24) and corrects itself - Just awesome engineering!
You have to see the first one, to realize how funny the second one is!!! That part with the girls on the park bench (1:10) and the 'running man' dance (1:13) is hilarious.
