Music Room. Finn puts some awkward moves on Quinn, who gently rebuffs them, but that's not important right now because what is important right now is the fact that The New And Improved Justin Bieber Experience has arrived to dazzle everyone with their very first Bieb-tabulous performance as a quartet. Each of the gents involved, by the way, has lovingly teased his luxurious locks forward across his brow with the exception of Puck, who's got a miniature Bieber-fringe merkin stapled to the front of his hood. Yes, it is as ludicrous as it sounds, but every single Glee Gal present again seems utterly smitten nevertheless. And with little further ado, the boys hurl themselves into their version of this hot mess, and I really have nothing to say about this particular performance -- which, incidentally, begins in the music room before magically transporting itself over to the McKinley High auditorium -- because I'm pretty sure I got the point the first two times around.

And when it's over, Single-T Tina and Brittany leap onto the stage to sprinkle a little sugar on their menz, while Quinn quietly approaches Finn to confirm that she'll not be stepping out on Lady Lips anytime soon, much to Frankenteen's chagrin. Elsewhere, Puck hops down into the auditorium proper to ask of Lauren Tuna, "So, what'd you think?" "Honestly?" Lauren admits. "Although my love would crush him, I'm totally turned on by the Biebster -- that is, until I remember that he looks like he's twelve, and then it's sorta creepy." Taking all of that into consideration, she grants Puck's performance a disappointing C+. "Listen, Zizes," Puck levels with her, "I'm dying here -- you got me every which way, and we both know I'm not the brightest, so please: What do I have to do to get inside of you?" Or maybe he said "with you" in that last bit. I can't be sure. In any event, Puck's in luck, as Lauren might have a "proposition" for him, but again, he'll have to wait until she gives him the signal.

Back on the stage, Quinn flirtatiously ambles up to Lady Lips to confirm their appointment at Color Me Mine that Friday night. As she exits, Sam allows himself a little fist-pump of triumph, but his joy is short-lived, for barely has Quinn disappeared into the wings when Santana saunters over in full maneater mode to coo, "Sammy Evans! You are Bieb-a-licious!" Lady Lips blatantly ogles her ample cleavage as Santana continues, "How are things going with you and Quinn?" "Fine," Sam insists, and with vast amounts of faux concern flooding her tone, magnificently malicious Santana replies, "No, they're not." Lady Lips is dumbstruck. Well, you know, more than usual. "You and I should talk soon," Santana coyly adds with a saucy little head-tilt thrown in there for good measure, and with that, she slinks off into the shadows, leaving a thoroughly out-classed Lady Lips to flail around helplessly in her splendiferous wake until the camera finally cuts away to the next commercial break.
