Swept away by a hurricane, Peter and his pals Quagmire, Joe and Cleveland manage to float to safety by using one of Quagmire's sex dolls as a raft (and don't ask what they ate during their ordeal!) Meanwhile, the town of Quahog holds a memorial for the "lost" neighbors, while Peter's wife Lois marries their family dog Brian, who is supporting the family as a used-car salesman. The fun begins when after four months, Peter returns, placing Lois in the awkward position of cheating on her husband WITH her husband! This inside-joke-studded spoof of the Tom Hanks movie Cast Away was ironically bumped from its scheduled September 11, 2005 telecast date due to ongoing news coverage of Hurricane Katrina.
