One of the more interesting aspects of this episode was finding out that Misaki was getting her driver's license. It's rare to see that at all in high-school animes. I always assumed it was because Japan's public transportation infrastructure was generally good enough to make vehicles irrelevant for most people, like in NYC. Here in the states, getting your driver license in high school is a pretty big deal because it's seen as a sign of nearing adulthood.
The other interesting thing was the funny tune the dumb little sister would sing during scene transitions. To me, that was the best symbol of how silly the episode was
