Barney: Guys, guys. Guess what Robin just did?
[flashback to moments earlier:]
Barney: Are you crying?
Robin: I know it's stupid, but... [singing] And the dragon.... I'm happy, you know.
Barney: Not as happy as I am, Robin. Guys, guys. Guess what Robin just did?
[present:]
Barney: And then, I told you guys what Robin just did, but you were there for that. I got to tell the rest of the wedding. Aunt Meredith.
