Damn, two songs from Glee make it on here? I was watching this week's episode when suddenly they started performing "Afternoon Delight" by the Starland Vocal Band. I couldn't stop laughing. It's put to even better use on Arrested Development, the single-greatest show ever.
YouTube isn't helping with my search for an Arrested Development clip, so a weird reverse-video version from Glee will have to do.
