Trivia: This episode was the only episode to feature a single regular castaway from the show (other than Gilligan) to ruin a rescue attempt at the end. The professor was to blame in this one by making a mistake.
Trivia: Mrs. Howell was commonly referred to as "Lovey" by Mr. Howell and viewers know her by that name. Her first name actually was Eunice (though that name was never used in the show).
Trivia: As Ginger, the Professor, Mrs. Howell, and Skipper talk, look at the handled device on top of the cabinet. It's the valve created in Season 2, Episode 25, "Steam Heat", when the Castaways thought there was a hot spring on the island, and wanted hot water for bathing and dishes.
Trivia: Every cast member appeared in every episode.
