Marshall: Oh, I forgot the lullaby. Do you know Marvin's lullaby? We sing it to him every night.
[flashback to Marshall playing guitar and singing to Marvin with Lily adding percussion:]
Marshall: Night, night, little Marvin Stars twinkle for you [Lily plays chimes] The Dreamland train's a-chuggin' [Lily blows train whistle] All your dreams will come true And the horsie says, "Good night" [Lily plays wood scraper block] And the birdie says, "Good night" [Lily blows bird whistle] And the elephant says, "Good night" [Lily plays tuba] And the skeleton playing his own rib cage Says, "Good Night" [Lily plays xylophone] And the robot says, "Good night"
Lily: [uses a voice-changing megaphone] Good night.
Man: [o.s.] Enough with the damn music!
Marshall: [singing] And Mr. Nesbit says, "Good night" And the whole world says, "Good night" Take it, Mommy.
[Lily plays the violin]

Robin: I appreciate what you're doing. But I'm not chasing after Barney anymore. I just got done being crazy about all that. I mean, why would I want to throw myself back in that pit?
Ted: Because you're in love with him.
Robin: No, I'm not. I'm happy for him.
Ted: So, it doesn't bother you that Barney Stinson's gonna propose to another woman on top of the World Wide News building?
Robin: Wait, why the top of the World Wide News building?
Ted: I guess it's Patrice's favorite spot in the city.
Robin: Damn it, Patrice, that's my favorite spot in the city!
Ted: Whoa. [phone chimes] Ranjit says, "Whoa."

Ted: Look, I just appreciate you showing up at all on your big night away. I mean, Barney's not even gonna be there.
Marshall: What?
Robin: This is the biggest night of your career. Why isn't Barney coming?
Ted: I don't know. He said, "Legendary" and "Challenge accepted," and then he winked. "Wait for it," you know, all that stuff.
Marshall: That does sound like him.
