Gahhh, I hate when people sing along. I mean, sure - I mouth the words along sometimes, but I don't actually say them out loud. My friend was doing that when I saw it for the 4th time on Friday, and it was during, like, Finale B, so I was hysterically crying, so I was pretty pissed. But then I was just like, "Sshhhhh..." nicely, so then she stopped. All is good.
