In the 1989 sci-fi sequel Back to the Future Part II, Thomas F. Wilson delivers one of his most memorable lines as the antagonist Biff Tannen. The scene depicts Biff reacting with intense sarcasm and disbelief, exclaiming, 'Oh, that's rich! You're gonna make me rich!' while laughing in Marty McFly’s face. This moment perfectly encapsulates Biff's greedy and cynical personality as he mocks a seemingly absurd proposition. In the modern digital landscape, this clip has evolved into a versatile video meme template used to express skepticism toward 'get-rich-quick' schemes or to highlight the irony of a situation. It is the go-to reaction for when someone suggests a business idea that is either outdated or unintentionally profitable. Users often employ this clip to represent feelings of smugness, mock-excitement, or genuine surprise at a financial windfall. Example caption ideas include: 'When my friend suggests we start a dropshipping business in 2024,' 'Me finding a crumpled $20 bill in my old winter jacket,' and 'When the crypto bro explains how I will be a millionaire by next Tuesday.'
