When Hal and the garbageman get into a trash-dumping war (which benefits Dewey because the house ends up with a big pile of trash, which means Dewey can't get to school), he enlists Reese's help. Meanwhile, Lois gets her job back at Lucky Aide (on probation), and fights against Malcolm in order to take down an offensive store display of a smiling black janitor holding a mop and a 6-pack of malt liquor. Soon it's an all-out war between mom and son - until Lois encounters a fellow employee who offends her even more than the display does.
When the garbage man refuses to pick up a large scratching post, Hal gets furious and tries to get back at him,by trashing his lawn,which the garbage man counters by dumping a mountain of garbage on his lawn causing hal and reese to steal his garbage truck. Malcolm and Lois argue over a offensive advertisment at the drug store,while lois is trying to get rid of it for prejudice reasons. Malcolm thinks she's just trying to control him and it leads to a mother vs son battle. As Lois attempts to get rid of the advertisement by taking out of the store, she meets Shirley who appauds her. She tells her that she couldn't stand looking at it anymore and had to get rid of it. Lois is soon more offended when Shirley is revealed a racist who doesn't care for having different races at Lucky Aide and puts the advertisement back. Malcolm is soon revealed to hate the display, but also realises he won't escape from Lois' control.
