Is Pawnee big enough for three Tammy Swansons?!

We’re about to find out because Parks and Recreation has cast longtime Saturday Night Live writer/guest star Paula Pell to play the original Tammy in Ron’s life — his mother.

Pell, who also serves as a writer and occasional guest on 30 Rock, will debut as Ron’s salt-of-the-earth creator in an early Season 4 episode. Considering Pell is roughly the same age as TV son Nick Offerman, it’s fair to say Parks and Rec‘s makeup gurus will be adding a few wrinkles to her face. (A show rep ruled out the character turning up in a flashback.)

Tammy Zero’s arrival coincides with the introduction of Patricia Clarkson as Ron’s first ex-wife, Tammy 1, and the return of Megan Mullally as Tammy 2.
