I find it interesting that this famous Scrooge quote (which if I’m not mistaken is from not only the old cartoon but the comics as well) foreshadows the very life lessons each of the nephews can learn from their Uncle Scrooge (and in order, too).
Huey is the smart kid… smart in the bookish sense. When the triplets list off cool things they’ve heard about Scrooge, the things they list give us a clue as to what each of them value. Huey valued Scrooge’s intelligence, as his favorite story about Scrooge was about him solving the mystery of the Chupacabra.
I’m guessing one thing we’ll see about Huey in the future is that he needs to learn from Scrooge how to be “tougher than the toughies.”
Dewey most valued Scrooge’s valor, as he recounted the story of Scrooge defeating a rock giant and carving a statue of himself out of its leg.
We’ve already seen that Dewey is pretty tough, and valiant… to the point of foolhardiness, really. Thus Scrooge needs to teach him how to be “smarter than the smarties.”
Scrooge even gave Dewey one of his other famous lines:
Ah, the “evil triplet.”
Louie seems to prefer not to lift a finger. As we’ve now seen in “The Great Dime Chase!” he has rather lazy tendencies and would also like to make money through any means necessary, just so long as it’s easy. He was most excited to meet Scrooge because of how rich he is. He’d like to be rich, as well, and thinks that he is just because he lives with his rich uncle. Scrooge wasn’t about to stand for that, though. He’s teaching his nephew the importance of making his money fair and square.
