Mark walks in. (I would say something about Boy Meets World and Cory and how awesome he is/was, but I actually never watched that show; don't worry, though, Angel picked up my slack.) Heather reminds Mark who Jenny is, and Sarah seems to like him at least a little bit more than she likes Heather. Which, of course. Who wouldn't? They ask Sarah if she's going to the reunion this weekend, but she's not. In fact, I'm guessing the reunion committee was unable to track down "Jenny Burton," so this might be the first she's hearing of it. After all, she's probably not on Facebook or anything. Chuck walks in from the back room -- ignoring Sarah's instructions yet again -- for some frozen yogurt and backstory. When Heather tells him they all went to high school together, he makes an adorable Casablanca reference: "Of all the semi-tart, Asian-influenced frozen yogurt shops in all the towns in all the world, you walked into hers?" He gets them to tell him that Sarah/Jenny's from San Diego. And he has entirely too much fun with her new name, calling himself "Jenny's Chuck." Then he flashes on Mark, fakes brain freeze, and invites them on a double date that very night. Mark and Heather are so in. Let's just say Sarah's less enthusiastic. Then fun, bouncy Cake credits. Am I the only one who thinks it's weird Big Mike was added to the opening credits? Jeff, Lester, Anna, and Awesome I get, but Big Mike seems an odd choice. His character screams "recurring."
Speaking of Big Mike, he's at the Buy More setting up the episode's secondary storyline: He's going on vacation for a few days. He's leaving Lester in charge, and wants the employees to give Lester the same respect they give him, even if he is a scrawny-ass Indian kid with a Bay City Rollers hairdo. Then he leaves.
