The kids wants to play rough, to which Homer angrily berates them for and demands that they grow up. Embittered by his anger towards Homer, Bart punches a punching bag until Lisa tells him that he can punch better than that. She takes Bart's gloves, draws an image of Homer on the bag to motivate herself and Bart, and starts punching the bag. Upon hearing the sound the punching bag while sleeping on the couch, Homer complains to Marge about it and tells her to tell them to stop, but Marge likes the sound and asks him to do it until he demands her to do it immediately. Marge furiously bursts into the room, then the punching bag noise gets faster. Homer storms into the room, only to see in shock of Marge punching the bag. They all apologize to Homer, but Bart and Lisa refuse to let go of the punching bag, not wanting to infuriate him. After telling Bart to move aside, Homer orders Lisa to let go of the punching bag, only for it to hit him several times and knock him out. As the unconscious Homer lies inert, Bart raises Lisa's arm up, declaring her the winner.
