The Simpsons, season 9

The ninth season of the American animated sitcom The Simpsons aired on Fox between September 21, 1997, and May 17, 1998. It began with "The City of New York vs. Homer Simpson". Mike Scully served as showrunner for the ninth production season. The ninth broadcast season contained three episodes with 4F-series production codes, indicating that they were hold-over episodes from production season eight, and two episodes with 3G-series production codes, which are not explicitly confirmed to be part of any production season but are speculated to be relabeled 3F-series episodes. This makes it the first broadcast season to include holdover episodes from two previous production seasons.
