8 - 12: Naked to the Limit, One More Time

Roger pretends to be Jeff's imaginary friend, so he can freely roam naked around the house with no disguise. But when big-mouth Jeff figures out that Roger is an alien, Stan issues an ultimatum: either Roger or Jeff must be killed immediately. Meanwhile, Steve becomes insecure about the shape of his rear end.
