Robin walks in to MacLaren's, where Marshall and Lily are waiting. Lily, especially, is waiting to respond to Robin's casual, "Hi guys," with this show's latest really-wants-to-be-a-catchphrase-but-there's-no-way-to-use-it-ever: "Where's the poop, Robin?" Robin says Lily's like a bomb-sniffing dog, but with poop. She's a poop-sniffing dog. Marshall thinks that's actually just a dog. Which, I have two of them and that's completely true. Robin admits that she called Don again. Cut to Robin's call. She's trying to be awesome and cool, all: Sorry. I saw you on the news and it made me crazy. But "I just wanted to say, from the bottom of my heart, I am going to kill you." Nope. Kidding again. "And that Asian slut on your Facebook page. She's dead too." Wow. Who knew Robin was this crazy? Lily thought Robin deleted his number, but Robin has it memorized, because, you know what? Closure doesn't exist and Robin will never have it. She says that no matter how much she tries to forget it happened, it always will have happened. They'll always be a loose end. They'll always be ...

Professor Ted completes her sentence: "... Unfinished." And he keeps teaching over the next scenes, making current Ted our narrator, which really demonstrates how much Bob Saget and Josh Radnor sound alike. It's almost eerie. Anyway, he talks all about things being unfinished and how we'll never know if we don't finish things as Robin stares at a picture of Don, Lily does karate with her fridge, and Marshall plays some funk music -- sad and alone.

Professor Ted narrates how hard it is to get things back once they're gone. He stops talking mid-sentence, and then leaves class. He runs across town, nearly getting hit by a bus (that's what killed the architect whose unfinished building he's lecturing about), and shows up at Barney's. Barney greets him and hot student Rachel. But no dwelling on that. He looks at Barney seductively, and Barney says he'll call Marshall to draw up the contract. But Ted says he's not that easy. Saget!Ted says he made Barney break his rule, and take him to dinner before he gave him the thing he allllllllways got. Ted toasts Barney: "Yes." Oh, they are so cute together. And Robin eventually got closure, too, as we learn with a flash forward of her seeing Don on the news, trying to call him, and not remembering the number. She hangs up: "Finished with that." And turns off her TV, which fades us to black.
