Amos & Andy: The Chinchilla Business, S4E1, 1955

Andy only has $50, but his girlfriend wants a fur coat. As it happens, Mama wants to start a business and the Kingfish needs to pay her back $50 for a surgery he had 8 or 9 years ago. The "rare chinchilla business" is what Kingfish decides to get Andy into so that Andy may get his girl her coat. Naturally, the Kingfish's plans don't work out.
