It's not their worst choice for a single.Say it isn't so was the worst choice.
in fact I think missunderstood has real potential to bacoming a moderate hit.I think it's catchy and poppy enough to get stuck in peoples head after the first listen,and the video is good enough and funny enough to become popular too. Hey if someone was to look for Bounce because of the missunderstood video they will be asking for the cd with that song with the funny video.

It wont become a huge hit but it could become a moderate or a minor hit.
