I don't care too much for Glee... I get the appeal, and I see it having an audience... but every time I tried watching it, I just couldn't get into it. Either the music sharply interrupts the plot or the plot sharply interrupts the music.
But considering I did manage to watch a few minutes of it right until after he sang Being Green. And here's the best part. The commercial break right before he sang that, the Muppet movie TV spot came on. Brilliant way to get exposure for the movie.
