After "Nowhere Man", Jeremy Hillary Boob, Phd., has realized how lonely he is living in the middle of nowhere, and starts to break into sobs. The other Beatles make it perfectly clear that they just want to get going and leave him behind, but Ringo feels sorry for Jeremy and asks him to come along. Jeremy is so surprised that they'd accept a "nowhere man", and Ringo just seals the moment with one last pun: "Yeah, c'mon, we'll take you someplace."
The moment in question:
Paul: (shrugs) I don't know. Ringo's just a sentimentalist.
Ringo: Aw look at him. Can't he come with us? (runs over to Jeremy) Hey, uh, Mr. Boob - you can come with us, if you like.
Jeremy Hillary Boob, PhD.: You mean... you'd take a nowhere man?
Ringo: Yeah. Come on, we'll take you somewhere.
When The Beatles tell the defeated Blue Meanies that they can be forgiven for conquering Pepperland and live there in peace and the Meanies accept. Particularly powerful, because the head of the Blue Meanies reveals that his cousin is the Bluebird of Happiness, and thus subverts one of the movie's primal leitmotifs- blue as a color of evil- by turning it into the color of happiness. Since when do the villains, once reformed, turn their powers around, rather than simply adopting the hero's powers and color set?
What makes it even better is the It's All Too Much segment right after. The scene of Jeremy and the Chief Blue Meanie becoming friends is just adorable. That and all the other characters, villain,Pepperlander and Beatle alike, getting together and having a party.
