Robin: It wasn't me.
Lily: What?
Robin: I'm not the one who cried at Clint's song.
Ted, Marshall & Lily: [gasp]
[flashback to Virginia and Clint's wedding:]
Robin: Are you crying?
Barney: I know it's stupid, but... [singing] And the dragon [talking] They're just so happy, you know.
Robin: Not as happy as I am.
Barney: I will give you $500 if this just happened to you instead of me.
Robin: 500 bucks? Deal.
Barney: Thank you, Robin. You just saved me unspeakable public humiliation and shame. Guys, guys. Guess what Robin just did?
