Sanford and Son (1972)

S2E7 Have Gun, Will Sell

One night, Lamont and Rollo head out for some fun. Upon returning home, they stumble upon a burglar making a hasty getaway. They soon find that the thief has left behind his firearm, and in a bid to make some easy money, they plan to pawn it. At the pawn shop, however, the broker misinterprets Fred's request for cash in exchange for the gun as an armed robbery.
