The 'And That's When the Big Bucks Start Rolling In' meme originates from the 1992 episode of The Simpsons titled 'Homer at the Bat.' The scene features a character confidently presenting a strategy for financial success that is clearly overly optimistic. On the internet, the template is used to satirize 'get rich quick' schemes, the 'grindset' culture, or the meager profits earned from minor side tasks like selling items online or participating in surveys. It perfectly captures the hilariously misplaced confidence of someone who believes they are on the verge of a massive windfall from a very small or absurd investment.
