"The hair was Step One," Sam's voiceover narrates as the shot cuts from the bathroom to a reception hall, where a series of Mylar balloons spell out "MAZEL TOV" as they float above the heads of some very bored-looking adolescent girls. "Step Two," Sam's voiceover continues, "was booking a couple of bat mitzvah gigs to test how my new one-man band would go over." Lady Lips, now clad in a Bieber-appropriate hoodie, steps up to a microphone with his guitar, introduces himself as -- wait for it -- "The Justin Bieber Experience," and launches himself into a tentative cover of the unbearably monotonous "Baby." The young ladies present ignore him for the first few "notes," choosing instead to futz around with their Androids, until The Power Of The Biebs -- a fearsome force, even by Lady-Lips proxy -- overwhelms their collective sense of good taste, and they rise up as one to rush the stage in a tight, frenzied, mutant knot of grasping claws and near-ultrasonic shrieking that propels Sam backwards over his amp. And as he lies there on his back with that pack of adolescent harpies caterwauling above him while they reach down to pet at his irresistible coif, Sam's voiceover smugs, "Heads up, Quinn Fabray: You're about to be hit head-on with The Full-Blond Bieber!"
"We need to talk!" Rachel frazzles back at McKinley as she chases after Brittany on that outdoor walkway no proper Ohio high school is without. "Why are my legwarmers on your arms?" Brit-Brit is, indeed, sporting a pair of comfy-looking magenta legwarmers on her otherwise bare forearms, and she blithely shrugs by way of response, "I got cold." "But we had a deal!" Rachel whines, and long story short, that deal pretty much amounts to this: As part of Rachel's "career resurgence," she intends to "dominate discussion" by launching "a trend or two." To that end, Rachel gave Brittany half of her allowance to take one of her "signature" looks and make it popular. Brit-Brit dimly remembers that they agreed legwarmers had a better chance of taking off than reindeer sweaters, which is right, but Rachel insists the scheme won't work if Brittany wears those legwarmers "incorrectly." "Can I wear them that way tomorrow?" Brittany asks, explaining, "I wore a tank top today because I thought it was summer -- no one ever taught me to read a calendar." Rachel can't deal with that particular bit of nonsense at the moment, so she hastily agrees with Brittany's proposal, so long as Brittany remembers to announce to all and sundry that she got her legwarmer inspiration from none other than Rachel Berry herself.
