It's Secretary's Day, and Andy wants to make it super-memorable for Erin. Which it is, but not in the way he planned. He pushes Michael to take her to lunch, where Michael, at a loss for conversation, clumsily reveals that Andy and Angela were once engaged. Erin takes it badly, to say the least, and angrily disrupts the office Secretary's Day celebration.
Jo Bennett's flunky, Gabe, spots a chance to demonstrate his authority in a crisis, but not the crisis described above. Instead, it seems Oscar has made a parody web video combining footage of Cookie Monster with Kevin's voice, and the teasing penetrates even Kevin's thick skin. Gabe's plan to act bad-ass by banning the whole topic backfires when he tries to suspend Jim and Pam without pay, only to first learn that he can't do that and then watch helplessly as the Halperts head home for a couple of fully-compensated days off with Cece. And now the office is mocking him, as they should.
Erin dumps Andy, and Michael finally figures out how to talk to Erin: having to cheer her up by acting like a big old dorky-dork. How did he not realize that was her sweet spot?
Just about everyone is gathered around Oscar's desk, watching a video of Kevin's voice set to footage of Sesame Street's Cookie Monster that Oscar has put together. Kevin joins the group, expecting to laugh with everyone else, but when he sees what's going on he pouts on past to his own desk, refusing requests to say "Me eat cookie." Everyone else wants Oscar to send them the link. "Angela, this is inappropriate!" Kevin appeals. She simply laughs, "This is my favorite day!" I don't know, it might be worth the mocking to have one day of sitting across from Angela while she's in a decent mood.
Andy's extremely excited about Secretary's Day, which happens to coincide with his and Erin's three-week anniversary. He's sent out multiple reminders to everyone, and they're stepping up, with everyone dropping off gifts, up to and including a bushel of beets from Dwight. "If it wasn't for secretaries, I wouldn't have a stepmom," Andy tells us happily. Another one of those jokes that's funny because it tells a story.
It also seems to be Pam's first day back from maternity leave, and she tells us how that went: "It rocked my ass off!" There's a dead plant on Pam's desk, which Jim didn't water because he didn't know it existed until this second, and Dwight didn't because "I chose to let it die." "Nice to see you again, Dwight," Pam says unconvincingly.
Andy's in Michael's office, leaning on him to take Erin out for lunch. Michael isn't sure: "She's kind of a rube," he says doubtfully. And not in a talking-head shot, either. Andy takes offense, but only until Michael agrees to lunch. Michael heads out to reception to ask her, and she even gets a picture of it happening.
In the break room, Meredith offers Kevin a cookie, but he refuses until Darryl says they're his birthday cookies. Kevin apologizes and accepts. "Nom nom nom nom!" Darryl teases. Kevin THs, "They're making fun of Cookie Monster. I get that. But in a strange way, it feels like they're making fun of me." Like Darryl sad, that's some stone-cold narcissism.
Kevin shows the video to Gabe, who at least acts sympathetic, calling it "violent and offensive." He offers Kevin a box of tissues, even though Kevin isn't crying. "You have some food on your face," Gabe explains. Then Gabe THs about how this is a chance to finally assert his authority with the Scranton crew. This should go well. In the bullpen, Gabe announces to everyone that talking, joking, or forwarding the video is now banned. He adds that this comes straight from corporate, so they'd better listen, and signs off with a dark, threatening, "Ciao." Which is just as dark and threatening as that sounds, which is to say, not at all.
