Music Room. Rachel and Finn -- dressed up as a nun and a priest, respectively -- unleash their carefully prepared obnoxiously bad/badly obnoxious duet upon the rest of the class, and it's Billy Preston and Syreeta Wright's "With You I'm Born Again," and it's exactly as gross at that set-up sounds. So gross, in fact, that it leaves Mercedes, Sam, Tina, Quinn, Mr. Schue, and yours truly with an overwhelming desire to punch Rachel and Finn in the face. Rachel and Finn are shocked -- shocked -- at the others' reactions, and take to their seats, abashed, all the while hoping this gruesome mishap doesn't cost them the competition. Eager to get things back on track after the late atrocity, Mr. Schue calls on Sam and Quinn for their competition entry, and it's "Lucky," an unbearably twee bit of nonsense from Jason Mraz that leaves yours truly and exactly no one else with an overwhelming desire to punch Sam and Quinn in the face. And as she basks in the wrongheaded adulation of her peers, Quinn allows her hand to linger in Sam's for just a moment too long before we head into the next commercial break.

And just how did Artie find out that Brittany's using him for his voice, and that's the only reason she had sex with him?
