Just as Michael goes off to "tell somebody," Dwight stumbles from the building. He has an announcement to make. It turns out that Ryan left a cheese pita in the toaster oven, and that's what started the fire. Dwight beams psychotically and holds the black ex-pita aloft like a trophy. Ryan looks mortified. In a TH in his office, Michael laughs hysterically about Ryan starting the fire. If you don't know that this is going to end in Dwight and Michael singing a "Ryan Started The Fi-ah!" song, then you don't know Dwight and Michael. Ryan THs that he can't believe he started it. As they sing, Katy pulls up to pick Jim up for lunch. She gets out of the car, telling him she knows her answers to Desert Island. Jim gathers the group, and Katy says her first answer is Legally Blonde. Naturally, Pam laughs. This is the one Jim mocked her for liking, you'll recall. Pam THs that she forgot Katy was such a "super-nice girl," and that she and Jim are cute together. Not really wanting to know what the rest of Katy's movies might be, Jim calls the game on account of...his own discomfort, really. He and Katy leave for lunch. As they do, Pam pulls Roy into a passionate smooch. Jim does not look pleased by this, but Katy comments that Pam and Roy are "so cute." Jim and Katy are so cute! Roy and Pam are so cute! Repression is so cute!
Dwight, now joined by Kevin, torments Ryan some more about the fire. And then, in a TH much later, Dwight is still singing the song, and he is still clutching the burnt-out pita, thrusting it toward the camera. In a TH, Michael says that Ryan is book-smart, and he's street-smart...and book-smart. He promises Ryan the rest of the rules tomorrow. This is the part where Ryan should have known what he was getting himself into.
