Lois's meager hopes for a happy birthday are dashed when Hal forgets the day completely, Reese, Malcolm, and Dewey spend the money she'd given them for a present mostly on themselves. At her wits end, Lois runs away from home and goes to a batting cage.
Meanwhile, Francis comes home to celebrate his mom's birthday. He convinces an African woman that he picked up on a bus to attend a party with him at his mom's house before going to Ritchie's house for his usual keg party. However, when he arrives too late and that Lois is gone, he doesn't hesitate to set his younger brothers' straight for their selfishness.
Hal and the boys throw together a makeshift party for her at the batting cages. Lois isn't impress because she fells like it's the best that Hal, Reese, Malcolm and Dewey can give her. She asks them to show her some consideration in future. Hal honestly tells Lois that isn't something they're smart enough to do and can only offer her their total obedience. The lead clown unsympathetically insults Lois by pointing out she should be grateful that they're trying for her and she shouldn't be a shallow bitch to her family. Hal is offended by this and doesn't hesitate in retaliating by calling him out for insulting her. He punches the lead clown for it. This kicks off a massive brawl between the boys and the other clowns, and seeing the lengths her family would go to defend her makes Lois realize how much they truly care.
