Two Days Before the Day After Tomorrow/Trivia

Trivia

 * This episode is a parody/statement of the Katrina disaster in New Orleans.
 * The Crab People theme playing in the background after they are accused of being responsible for the flood, and several people looking around for the source of the music, implying it could be heard by the characters and not just the audience.
 * This is one of the few episodes where Cartman and Stan are joined together and primary focus without Kyle, Kenny, Butters or another friend.
 * Liane Cartman does not appear in this episode and no one shows concern that Cartman is missing.
 * Kenny is shown riding in the boat with Cartman and Stan in one scene, but is not seen again throughout the episode.
 * At the end of the episode when the town's people are saying "I broke the damn", this is a reference to Spartacus.

Continuity

 * The Crab People are blamed as a cause of the Beaverton Flood. They were last mentioned in Quest for Ratings.
 * Randy has twice before been called on as the leading scientific mind in South Park. The first was Spontaneous Combustion and again in Die Hippie, Die.
 * Cartman claims to have an uncle Roy at the start of the episode. However, Stan has already met all of Cartman's extended family in Merry Christmas Charlie Manson!
 * One of Mrs. Garrison's breasts is damaged in this episode and leaks its contents. The damage done to the breast can be seen again in Go God Go, where one of her boobs is smaller than the other.
