Carl Reiner, Amy Poehler

How's this for your show of shows? TV Guide Magazine has learned exclusively that Parks and Recreation is set to host a living legend when comedy icon Carl Reiner guest stars as one of Pawnee's most powerful elders —and possibly a key player in Leslie's City Council campaign.

"Our research shows that, especially in local elections, really the only people who vote are senior citizens," says executive producer Mike Schur. "It's amazing. A very, very high percentage are retirees. So Leslie does an event at a senior center in hopes of winning the senior vote and [Reiner] is this sort of Godfather type figure — he's really the main guy who's endorsement you need to lock down. It's super cool. We are really excited."

Reiner's appearance is tentatively set for the season's 17th episode, which will also mark the beginning of Free Agents survivor Kathryn Hahn's recurring role as the advisor to Leslie's political rival.

Are you excited to see the combined power of Reiner, Hahn and the rest of the Parks crew playing together?
