Mercedes is at her locker. Puck gives her an appraising look and saunters up to her, and then delivers this gem of a speech: "Hey sugar. Listen, I got a proposition to make. I did some research. Blacks and Jews have a history of sticking up for each other. And Wikipedia says that King Martin Luther loved the Jews." Mercedes can't even begin to count how many offensive things were contained in that statement; I can't begin to count how many funny things there were. Puck tells her that the point is that he needs to regain some popularity, which he thinks they can do if the two of them join forces. He proposes some light making out, noting (truthfully) that he's pretty easy on the eyes. Mercedes: "Baby, I just am not attracted to you. Plus, I know what you do to the girls you date. You knock them up, and then you hang them out to dry." Puck points out that he wasn't dating Quinn, he was just screwing her behind her boyfriend's back. And he tells her that Quinn is aware that he can't be tied down: "I'm a sex shark. If I stop moving, I die." She cuts him off before he embarrasses himself further, telling him that they have nothing in common: "You're top 40. I'm rhythm and blues." You just come over here, Puck, and I'll introduce you to the joy of dance remixes.

Music room. Mr. Schue is telling the kids how disappointed he is in them for slacking off. He also clearly told them the source of his info, since the other kids are pissed off at Rachel for ratting them out. She tells them to shove it; she's sick of carrying their weight, especially since it's just a month to Regionals. I was going to complain about this show's inability to ever stick to a timeline, but I realize that there are actually just four weeks left until the end of the season, so "a month" is as good a fictional timeline as any other. Will wants to know why the kids stopped singing. For Finn, it was because all the male leads started going to Jesse. Which, I guess, means that in his mind there's never been any need for Kurt or Puck or Matt or Mike to ever sing a note, since they never get leads. Santana says that her sole job is to look hot, not sing. Quinn blames her laziness on the baby hormones. Brit-Brit: "There are so many lyrics." Will starts moralizing -- a chain is only as strong as its weakest link, they're all in danger of losing their voices, so their assignment for the week is to come up with a song that represents their own voice and sing it as a solo for the entire club. And although he stresses that they're all going to be doing that, don't start to think we'll actually hear solos from more than a handful of kids.
