Barney: My life is finally perfect, and that is never going to change. Fired up for dinner with my mom tonight?
Robin: Yeah. To help streamline the rest of our lives, you can always assume my answer to that question is no. I'm pretty nervous.
Barney: Nervous? Why? It's just gonna be two hours of "I love Barney the most". "No, I love Barney the most".
Robin: You're right. I may not even get a chance to talk.
