Big Dog

My sister sent me this video, and I think I got a six-pack from laughing too much.
I showed it to my friend and she wasn't laughing at all so I guess not everyone finds it funny.
It kind of looks like two people are walking, but it's actually a robot (hence the loud buzzing sound, which only adds to the humor) with a really good sense of balance.
It's really funny when the guy KICKS IT (0:36) and when it's slipping on the ice (1:25), but hey that's just me.
