Hal and the boys offer to watch baby Jamie so an exhausted Lois can finally get some sleep. Hal leaves the boys in charge while he goes to the Lucky Aid to pick up more diapers. While the boys are watching Jamie, three beautiful teenage girls arrive and woo Malcolm, Reese and Stevie away for the night, leaving Dewey alone with the baby. Meanwhile at the Lucky Aid, Hal doesn't have enough money for the diapers and Craig forces him to work. Back at home, Dewey concocts an elaborate bedtime story for Jamie involving each member of his family.
