The episode satirizes the "Little League Dad" trope, pushing it to the extreme where Peter views his son as a financial asset rather than a child.
After realizing Chris is actually good at something, Peter decides to be a supportive father by becoming Chris's coach. However, in classic Peter fashion, his "support" quickly turns into a scheme. He starts a secret sports betting operation, taking bets on his own son’s Little League games. The tension peaks when Peter bets against Chris in the championship game, leading to a moral (and physical) crisis. [S15E2] Bookie of the Year
