"Time Keeps On Slippin" is the fourteenth episode in season three of the animated television series Futurama. It originally aired on the Fox network in the United States on May 6, 2001. The title is from a lyric in "Fly Like an Eagle" by Steve Miller Band. Basketball and time-travel play a prominent role in this episode.

Representatives from the Globetrotter homeworld land in Central Park challenge Earth's honor on the basketball court, for no apparent reason. Professor Farnsworth accepts the Globetrotters' challenge, resolving to create a team of mutant atomic supermen to take them on. When he completes his work, he is left with a team of mutant infants which necessitates the Professor sending the crew to gather chronitons to accelerate their growth. Bender's objection that the particles in question were responsible for the destruction of an entire civilization is ignored. All the while, Fry is trying to woo an unreceptive Leela.

The crew returns with the chronitons, and the mutants' growth is successfully accelerated. The game proceeds, with Farnsworth's team of mutants maintaining a lead over the Globetrotters. But at the start of the second half, time begins inexplicably jumping forward. The Professor calls a timeout during which one of the atomic supermen is killed and Fry joins the team. Although the Earth team holds a substantial lead, and there are only two minutes left in the game, the Globetrotters win by unknown means during a time skip. The Professor formulates a theory that the crew's collection of chronitons has destabilized space-time, and will lead to the premature destruction of the universe.
