After finding an old family picture showing a brother she never knew she had, Lois sets out to find her unknown sibling. However, her father denies it, so she sneaks into her parents’ house to find information. When she finds out that her brother, Patrick, is in a mental hospital, she visits him, and releases him after having a brief conversation. Back at the Griffins’ house, Patrick explains that, after a traumatic experience involving Jackie Gleason, he holds a grudge against the obese. While he is released, his traumatic experience occurs towards Peter, since Peter is overweight. Meanwhile, after a physical with Dr. Hartman, Peter realizes that he is fat and starts an advocacy group for fat people’s rights.
