Walter's Problem

S2 E1: After a wild cocktail party, lasting most of the night, Walter faces a bad hangover and Maude's wrath -- but refuses to face the fact that he has a drinking problem. Arthur, who had almost as good a time as Walter (and feels almost as bad the next morning), makes a pact with Maude that they will all go on the wagon for a month, and Walter reluctantly agrees to join them.
