Battle Of The Network Shows

Season two begins with a look at a special two-part Diff'rent Strokes. The time has arrived for Mr. Drummond to officially adopt Arnold and Willis, but a con man played by the great Whitman Mayo (Sanford and Son's Grady) has different ideas. What will happen, how does Mrs. Garrett feel about all of this, and--more importantly--what's the bathroom situation in the Drummond household?!
