The episode title and the Temple World in general is an allusion to the adventure film Indiana Jones and the Temple of Doom.
One of Rippen's lines in the episode, "Throw me the idol, I'll throw you the whip!", is a direct reference to Alfred Molina's character in Raiders of the Lost Ark.
Mrs. Wiseman and Mr. Wiseman, Boone's parents, make their first appearance.
The title references the slang term "porcelain god" for a toilet, which comes from the longer slang phrase "praying to the porcelain god," i.e., vomiting into a toilet, derived from the comparison of the sick person bowed over the toilet bowl to the posture of a worshipper bowed before an idol.
