I Love Lucy - Season 3 - Eps 21: Bonus Bucks
A dollar bill takes a zany trip-with the Ricardos and Mertzes in hot pursuit. It's a winning bill (worth $300) in a newspaper contest. It belongs to Ricky, but he gallantly slips it into Lucy's purse. Gallant isn't necessarily smart: Lucy unthinkingly gives the bill to the grocery delivery boy-who gives it to Ethel in change. The wild ride has only begun!
