It's a Blunderful Life

S4, E24: In addition to growing financial concerns, Charles is worried about the bad habits the Powell kids are picking up from their grandfather Walter Powell. When Charles confronts him, Walter promises to set a better example. That night at the magazine store, Walter refrains from buying a lottery ticket when Charles reminds him of his promise. Instead, the next customer, Jake (Don Most), buys the winning ticket which, much to the dismay of the Powell family, is worth $100,000. Feeling responsible for ruining Walter's chance at striking it rich, Charles dreams of what life for the Powells would be like if he had not interfered.
