In hall, a still damp Sam tells Finn that he just joined the synchronized swim team. Finn tells him to keep it down, since combining glee club and synchro kind of invites a massive amount of mockery at McKinley. Sam doesn't care, because he'll get his letterman's jacket. And then a couple of hockey jocks deliver a synchronized slushying to Sam's face. Mercedes sees, and walks over to Sam with concern on her face. She starts to wipe the ice off his face when Shane calls over and asks her what's going on. She tells him that she's helping a friend, but Shane thinks Sam will pull through, and offers (in a kind of demanding way) to walk Mercedes to her next class.
Auditorium. Artie tells Will that he's sure the girls will try to "neuter" him by suggesting he use a romantic song for the proposal. But Artie thinks he should subvert expectations and lead with his hips. By which, Artie means show off his sexy dance moves to make Emma swoon. And then Artie launches into a mash-up of Maroon 5's "Moves Like Jagger" and the Rolling Stones' "Jumping Jack Flash," while Will and Mike Chang dance and Blaine, Puck and Finn sing backup. After they finish, Will tells them it's a great choice, but he's worried that the dancing will lead to sweating, which will lead to Emma freaking out. He leaves, and Mike Chang goes with him, much to Artie's dismay.
