Ultimate Slip 'N Slide was a planned American game show, based on the Slip 'N Slide water toy. The series was originally scheduled to premiere on NBC after its primetime airing of the 2020 Summer Olympics closing ceremony and hosted by Bobby Moynihan and Ron Funches.
On July 2, 2021, it was reported that production would be halted temporarily after a crew member contracted giardia (a.k.a. explosive diarrhea); On August 6, 2021, it was announced that NBC would not be moving forward the series. Although production was halted 7 weeks into the intended 8 weeks of filming, the format of the show, an ongoing competition with a definitive conclusion, meant that the final competition for the grand prize had not been filmed, and production's attempts to edit the show in absence of its proper conclusion were ultimately passed on. On August 8, 2021; the series was replaced by Family Game Fight! hosted by Kristen Bell & Dax Shepard in the post-Summer Tokyo Olympics time slot.
