Extract the celebrity guests that appeared on the show Parks and Recreation.

Numerous actors have made recurring guest appearances throughout the series, including Pamela Reed as Leslie's mother and fellow politician Marlene Griggs-Knope,[38] Ben Schwartz as Tom's fast-talking friend Jean-Ralphio and Jenny Slate as his twin sister Mona-Lisa,[39] Jama Williamson as Tom's ex-wife Wendy,[40] Mo Collins as morning talk show host Joan Callamezzo, Jay Jackson as television broadcaster Perd Hapley,[41] Alison Becker as newspaper reporter Shauna Malwae-Tweep,[42] Darlene Hunt as conservative activist Marcia Langman,[43] and Andy Forrest as Andy's frequent shoeshine customer Kyle.[44] Megan Mullally, the real-life wife of Nick Offerman, portrayed Ron's ex-wife Tammy in the second season's "Ron and Tammy", a role she reprised in later episodes.[45][46] Lucy Lawless and Jon Glaser have recurring roles in the fifth and sixth seasons as Ron's love interest and later wife Diane Lewis, and as Leslie's arch enemy on the city council Jeremy Jamm, respectively.
