Once again, the Griffin household is invaded by Peter's crabby father Francis, an old-line Catholic who hates anyone who doesn't adhere to his own peculiar set of religious values. In his efforts to re-convert the family, Francis causes little Stewie to become a "bubble boy." As a result, rebellious Peter attempts to establish his own religion, with "The Fonz" from Happy Days as his new Deity. Without revealing any more, please note that the episode's star-studded voice cast includes Marion Ross and Tom Bosley--and before we forget, Gary Cole is back as obstreperous boss-man Bill Lumbergh, the character he'd played in the movie Office Space (Shucks! There's no space left to mention Jaws: Fire Island).
