Plot Outline:
Lois makes Malcolm get a part-time job tutoring math, which he hates until he meets Nikki, a sweet, beautiful girl who wants to be his girlfriend. The only problem is Nikki's father, a Vietnam veteran, who likes to yell and is adamantly against Malcolm seeing his daughter. Secretly dating, Malcolm and Nikki must come up with creative ways to see each other without getting caught by Nikki's father. Meanwhile, Reese and Dewey discover a boy in the neighborhood who looks exactly like Dewey and begin terrorizing a bully, blaming their action on "Dewey's twin."
