Eric Carmen's "All By Myself" plays, but it's been filked into "All By Ourselves." Barney and Robin wander Manhattan's streets, seeing happy groups of best couple-friends, wherever they go. They enter a restaurant and ask the hostess for a table for two. She rolls her eyes and sneers. "Just the two of you?" They nod their heads in resignation and Robin covers her face as Barney leads her out of the restaurant. Later, in bed, they drown their sorrows in ice cream. And Barney's wearing an ice cream-stained white undershirt. No jammie suit! In the next clip, they sit on the couch, pigging out on various munchies. Barney suggests they call the weird ferret-owning couple down the hall for a game of Taboo. Robin says, "After midnight? No way. We can't Tabooty call them. It's pathetic." They can barely mumble out a hello when Ted walks in. His face wrinkles in disgust as he takes in their slovenly appearance. "Barney, are you wearing sweatpants?" Barney says, "Maybe. But they're Armani." Ted's had it. "I have some bad news for you, so I'm just going to come out and say it: YOU'RE A COUPLE!" He explains to them that couples need other couples. They need to admit they miss Marshall and Lily.

Dowisetrepla: Marshall, Lily, Py and Shea finish up a rollicking game of Twister. Shea compliments Lily on her last move. Py tells them they're the best. Marshall gives him a high-five. "Right back at ya!" Then, there's a knock on the door. When Lily answers it, no one is there, but something is. An egg timer. As it ticks away, Marshall joins Lily to see what's going on. When the timer finally dings, they go out into the hallway. A few feet down, there's another ticking timer. When it dings, they walk further down the corridor... Eventually, they make it to their building's entry. Outside, in the pouring rain, Robin and Barney are waiting on the sidewalk. Barney's holding out the last timer. They both say, "Ding." Despite the deluge, Marshall and Lily descend the front stairs to confront them. Robin offers them the timer. "For charades." Lily smiles and starts to take it, then draws her hand back. "How do we know you two won't hurt us again?" When Robin says, "You don't," Marshall tells them they have two wonderful people up in their apartment who are their perfect couple best-friends match. Barney says, "Then what are you doing standing out in the rain with us?" Lily says, "Damn it! Why is there something so attractive about a bad boy?" She looks from Barney to Robin. "And girl?" Hopeful, Marshall looks at his wife. "I think we can change them." Lily sighs then says, "Come here, you two." And the four drenched, star-crossed best couple-friends embrace in the rain, as the music (and who can blame it) swells (apologies to Joss Whedon). Barney pulls back to tell Marshall, "We'll never sleep on the Gouda again."
