Teachers' lounge. Emma, with a queasy look on her face, asks Coach Beiste about her lunch. It turns out the Panther has just discovered Turducken, and she's tucking into one with her bare hands. She's stuffing herself with protein to keep up her energy, which is depleted by her work on the student elections and her busy evenings with Cooter. She's grateful for their offer of help counting election ballots: "My quadriceps have been trembling like jelly all day. Cooter really pushed me to my limit last night." But she's talking about weightlifting, not Cooter-lifting. But that's okay with Coach -- she's decided that Cooter is the only guy for her.
Which is a nice segue to Puck in the music room singing Melissa Etheridge's "I'm the Only One." Although it's part of the Lady Music lesson that's supposed to be all about supporting Santana, he spends most of the song giving the sex eye to Shelby. She's sitting right behind Quinn, who thinks the sex eye is intended for her until she realizes that Puck is really looking at Shelby. Kurt, by the way, is wearing the same shirt he wore in his earlier scene at his locker, which is not the sweater he was wearing when he sang to Santana. Is it more likely that the editors would mess up the order of scenes, or that Kurt would wear the same outfit twice in the same week? At the end of the song, Puck dedicates it to Santana, telling her that he's glad he could be part of the phase where she slept with dudes.
Quinn approaches Puck at his locker to tell him how hot he was singing the song. But she thinks something's wrong with his eyes, since he spent the entire song staring at Shelby. He stammers for a bit and then tells her he was trying to get the message across to Shelby that he and Quinn are the only ones she should trust to take care of the baby. "That song was mainly about babysitting, for me." Quinn: "My mom is going on a Christian wine-tasting boat down the Ohio River on Friday." She invites Puck to come over to rekindle the love he felt for her after Beth was born. Puck's not interested, so she makes it clear that she's offering sex. But Puck shoots her down, since he's learned over the last couple of years that she's kind of crazy. So he'd "rather raw-dog a beehive." I don't even want to know what that means.
