George takes a second job selling encyclopedias with Uncle Willy to make ends meet after the family refrigerator starts failing. After an abortive start, he soon becomes salesman of the month--he even convinces Sid to buy a set!--buying not only a new refrigerator but bicycles for the boys, and finally reducing his hours at the post office so he can sell full time. Then he has second thoughts after he reads one of the contracts closely and discovers the payment conditions seem a bit shady.
