In F. Scott Fitzgerald's novel, "The Great Gatsby," it is mentioned multiple times that Gatsby's laughter sounds like money. For example, in Chapter 3, Nick Carraway, the narrator, describes Gatsby's laughter as having "an unqualified optimism" and that it "sounded like money." Additionally, Gatsby's extravagant displays of wealth throughout the book further emphasize the association of his laughter with the concept of money.
