Parks and Recreation showrunner Mike Schur has revealed that the episode will centre on Leslie (Amy Poehler) and Ben returning to Partridge, where Ben had briefly served as mayor before being impeached for a bad business scheme.
"The mayor is throwing a ceremony to say, 'It's okay, Ben. Everything's fine now'," Schur disclosed.
Several high profile guest stars have appeared on Parks and Recreation this season, including US Vice President Joe Biden, Jason Schwartzman and former SNL star Jenny Slate.
Amy Poehler recently said that her dream Parks and Recreation guest would be Bill Murray playing the mayor of Pawnee.
NBC airs Parks and Recreation on Thursdays at 8.30pm ET.
