Captain: "We stand witness today to celebrate the union of Lily and Marshall. Today, you two will become one, sharing your lives, the happiness, the sadness, the frustrations and the joy..."
Ted: This is pretty cool. I can't believe you never want to get married.
Robin: I never said "never."
Captain: "...to declare your love and devotion to each other in front of friends and family, all the people who matter most to you." What was that?
Marshall: What was what?
Captain: That little look. You two just shared a look.
Lily: We don't want to do this.
Marshall: We don't.
