Barney: Lily, something amazing has happened. I was talking to Robin, I was all set to tell her how I feel, but before I could, you'll never believe what she said.
[flashback:]
Robin: I think I'm in love with you.
[present:]
Lily: Aw, what did you say?!
Barney: What do you think I said? What would anyone say to something like that?
[flashback:]
Barney: Yeah. Robin, listen. You're great. I mean, you're really awesome, but I mean, we're friends. It's probably a bad idea.
Robin: I guess you're right. Have a good party.
Barney: [chuckles] You too, kiddo. [ruffles her hair]
