"Ten years ago today, the first episode of @nbcparksandrec aired," Jones wrote on Instagram last night. "And thus began the most magical seven years of my professional life playing Ann Perkins and working with kind, hilarious, and talented people that I still call friends. The cast, crew and writers spent a decent amount of time worrying about getting canceled, we nervously waited for our (usually) very low ratings mornings after we aired and, every season, we prayed that we would get picked up, even if it was just for six more. Because we loved it. Needless to say, over time, many, many people have come to love the show with unexpected fervor. I don't know if the series would have been what it was if we could've foreseen that. Holding onto each other tight and treasuring every moment together was a huge part of what is on screen. So grateful for this show, these people, this writing, this experience." ALSO: Watch Amy Poehler and Nick Offerman's video tribute to Parks and Rec on its 10th anniversary.
