Barney: Lily, can't you just let us be happy?
Lily: You're not happy. You just think you're happy because you feel happy.
Barney: And that's not happy?
Lily: Of course not. You and Robin need to have the talk.
Barney: Why? Give me one good reason.
Lily: I'll give you 20...
Barney: Wow, You can't even think of one. Headlights. Dear.
