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]
