Parks and Recreation is set to hit a major milestone this season: its 100th episode. Amy Poehler and Parks co-creator/showrunner Mike Schur will be writing the special episode together, Schur tells TV Line. “We didn’t want to be super meta about it,” he says. “We just wanted it to feel like all of our characters had reached a milestone in their lives, so that was the idea of the story going in. It’s a really good story with a lot of juicy stuff in it.” This will be the fourth episode of the show Poehler has written and the first she and Schur have written together. The 100th episode will be the 10th episode of the upcoming sixth season and should air sometime late this fall, with Rashida Jones and Rob Lowe set to exit the series in episode 13, just a few episodes later.
