Season 2: Episode 09: Holy Crap
Peter's dad is forced to retire from the mill. A stern workaholic, the elder Griffin does not take retirement well. When Peter and Lois suggest that he come spend some time with them, Peter's dad agrees, and Peter gets excited at the prospect of bonding with his father. But the new living arrangement doesn't go according to plan: In addition to being a workaholic, Peter's dad is also a control freak. He tells the children what TV shows they can watch, tells Peter how to spend his free time and instructs Lois on how to raise the kids. Peter decides that the best way to get closer to his father is to bring him along to the toy factory, but this plan also backfires. Peter's boss is impressed by the retiree's work ethic and hires him as a foreman, ensuring widespread misery at the plant. After Peter's dad increases work hours and implements strict rules, Peter is desperate to make him quit, and tries to convince him to participate in a plot to kidnap the Pope. The Pontiff is also impressed by the retiree's ambition, and offers him yet another job.
