Double Trouble (1941)

The owner of an American bean cannery and his wife are expecting the arrival of two orphans from war-torn England, but the "youngsters" arrive and are two addled-brain adults, Albert (Harry Langdon) and Alfred Prattle (Charles Rogers). Making a worse deal out of a bad one, the owner puts them to work in his cannery where, among other mishaps, they manage to place a $100,000 gem in a can of beans. The word gets out and customers, hoping to buy the can with the gem, clear the market place of the company's beans.
