It was a gotcha episode of 'How I Met Your Mother' (Mon., 8PM ET on CBS), picking up on events right where we left them with Robin and Barney in the bathroom of Marshall and Lily's suburban house. And once Barney stopped getting punched in the face for saying the wrong thing, he revealed he was excited to be a father.
Robin then borrowed the conceit of the show, by talking to her future children, telling them their story. Only their story turned into little more than a fantasy, as it was slowly revealed throughout the episode that Robin not only was not pregnant right now, but she could never have children. For a girl who never wanted kids, this should have been great news.
