It's a good thing that school is a snap for whiz kid Malcolm (Frankie Muniz) -- because he'll need all his mental powers to come out on top in the Wilkerson clan, who would stymie even the best of professional counselors. In the Emmy-winning sitcom's sixth season, the family faces hard times when Hal (Bryan Cranston) loses his job. Later, Dewey (Erik Per Sullivan) tries his hand at writing opera, and Lois (Jane Kaczmarek) enters a beauty pageant.
