"Two Days Before the Day After Tomorrow" is the eighth episode in the ninth season of the American animated television series South Park. The 133rd episode overall, it originally aired on Comedy Central in the United States on October 19, 2005. In the episode, Stan and Cartman accidentally destroy a beaver dam, which causes a catastrophic flood in the nearby town of Beaverton. To avoid punishment, the boys allow the townfolk to be misled into believing that the dam's destruction was caused by global warming, which triggers panic and mayhem around Colorado and across the country. The episode was co-written by series co-creator Trey Parker and Kenny Hotz. It parodies the 2004 film The Day After Tomorrow, and also general responses to Hurricane Katrina, particularly the various ad hoc explanations for the increased level of suffering from the hurricane and its aftermath.

Cartman reveals that he lied about the boat belonging to his uncle and convinces Stan to try to hide their involvement by maintaining complete silence about the incident.

Nobody tries to help the situation; instead, everybody would rather figure out who is to blame. At a conference at the Governor's office with top Colorado scientists and government officials, they all declare that the disaster is the result of global warming. At first, it is determined the full effects will take place on "the day after tomorrow". However, some scientists suddenly burst in and state that it has been proven that the disaster will take place "two days before the day after tomorrow". The declaration of the scientists causes mass hysteria, and everybody runs from "global warming". Most of the South Park people crowd in the community center. Randy authoritatively states that global warming is causing an ice age outside that would kill them if they left. Stan admits to Kyle that he and Cartman were the cause of the Beaverton flood (although Stan takes most of the blame). The trio then set
