NBC’s Parks and Recreation is gearing up for its grand finale, and some old friends are set to show up throughout the season. In addition to previously announced guest stars Megan Mullally, Rachel Dratch, and Werner Herzog, Rashida Jones and Rob Lowe are confirmed to make a one-episode appearance next season reprising their roles as Chris Traeger and Ann Perkins. “We made a list of people that we needed to see back one more time. We didn’t get everybody we wanted, because some people had other obligations,” Mike Schur told TV Line . “But a lot of the people we were hoping to see one more time — we managed to make that happen.” Another one-more-timer will be Jon Hamm as National Parks employee Ed: “If I have my way, every episode where you see events that take place before that moment will include a shot of him doing something insanely incompetent,” Schur told EW.
