This is how far Glee has come:
A few months ago, the show had yet to even air on Fox. Now, it's gotten so huge that the cast is releasing singles that won't even be featured on episodes.

Meanwhile, we've posted an actual clip from this week's mid-season finale. Watch various characters discuss Quinn's baby daddy - and, most urgently, how to keep the news from Rachel - in this scene from "Sectionals."
