Yesterday, I was talking to my dad about the game, and he was going on about how "at one point, I turned to (my sister) and said 'look! everyone's jumping around!'" See, he had no idea the song was going on, and I'm sure even if he did hear the song, he wouldn't have gotten the "jump around" part.
Anyhow, he thought everyone was just jumping out of pure bliss. 50k people (except him) were all just so happy they felt compelled to jump up and down.
I thought that was pretty funny. I mean, parents, right?
