I admit that I didn't really understand this. I mean, it was weird not seeing the other characters. I'm not even a fan of this series and I know the characters well enough! I couldn't tell who he was at first. I thought he was someone watching the commercial. Then again, he did look the same.
It was funny to see that live-action stuff on the TV. The animation is pretty good. I wish there was a final punchline. It was just something about a pervert robot. It seemed like it was cut off early.
