Upon discovering she has a brother named Patrick (Robert Downey Jr.), Lois dutifully arranges for him to be sprung from the mental institution where he's lived all his life. At the same time, Peter organizes the Society for the Acceptance of Fat Men--only to watch his membership rapidly dwindle as the fat men of Quahog are strangled, one by one, by an unknown serial killer.

And remember: "Ball in a Cup, Ball in a Cup, It's a ball in a cup!"
