Plot (Spoiler)

After being attacked by an octopus at the aquarium, Peter decides to become physically fit, and spends a mere fifteen minutes at the gym, then believing that he is now fit. Later, former U.S. President Bill Clinton’s car breaks down outside their house, and Peter, thinking he is strong enough, attempts to lift the car without a jack, which results in him getting a sudden severe hernia and being hospitalized. Depressed at the concept of becoming old, he confides in Clinton, after he visits Peter in the hospital, who tells Peter that age is only a state of mind. When Peter recovers, Bill takes him out to help him realize he can still have fun, but things eventually get out of hand when they start smoking marijuana, then steal things and cause mischief while high. Meanwhile, Stewie and Brian attempt to be toilet trained by buying an instructional video hosted by Roy Scheider (appearing as himself), but Brian persists to leave his feces in the garden, thus making Lois force him to wear a diaper.
