It's Monday morning. After two whole months of being grounded, the boys are excited about finally being able to watch television and to go outside. The trouble started when Malcolm (Frankie Muniz) and Reese (Justin Berfield) bet on Dewey's (Erik Per Sullivan) bike that one of Francis' (Christopher Kennedy Masterson) friends wouldn't eat a dog food sandwich. The boys lost the bike, and told Lois (Jane Kaczmarek) that it was stolen. They still don't know how she knew they were lying. Hal (Bryan Cranston), eager to watch wrestling again, begs the boys to behave as he leaves for work. Lois is home sick with a horrible case of the flu, and when the boys go by her room to say goodbye, they realize that she still thinks it's Sunday, the last day of their grounding. Malcolm impulsively decides that they'll go along with Lois' delusion and skip school for the day. They quickly grow bored, sitting home with no TV. Francis calls with some advice (to go to the arcade) and some information (where Mom keeps her money and how much they can swipe it without her noticing), and asks Malcolm to hide a very incriminating letter that came in that day's mail. The boys later discover that Lois, in her delirium, will answer all of their questions truthfully. They eventually ask how she knew they were lying about the bike and learn that Francis ratted them out. Meanwhile, Hal stops by the local Porsche dealership, where a smooth-talking dealer (Peter MacKenzie) gets him thinking about making a purchase.
