He wakes up in a stock before a judge and jury, where he learns that he is charged with being neurotic and erratic. The beagle appears in the scene and gives a testimony that the father hit him, and then he kicked him. The jury finds that he has no mentality because he does not massage his gums, and is childlike in his dental knowledge despite the fact that he attended college, and so finds him guilty. The judge reveals himself to be Bobby, and he sentences his father to the youth machine, which turns him into a baby. Bobbys father wakes up from the beagle licking his face. He sees the Ipana sign that concludes that Bobby is smart and begins acting kinder to him. Bobby, his father, and his friends all go out for sundaes and go fishing in the river.
