Ron Swanson Shaves Mustache For Tammy 1 On 'Parks & Rec' (VIDEO)

Fans of "Parks & Recreation" waited a long time to find out who would play Tammy 1, Ron Swanson's frightening ex-wife, and to see what kind of damage she could inflict on him. The season premiere did not disappoint, but this week's episode saw Tammy 1 do her worst by getting Ron to shave his mustache.

And the manipulation didn't stop there. When Tammy tells Ron he's being audited by the IRS, he gives her full control of his life, including his attitude, clothing and, yes, facial hair. In the snippet below, Ron enters the Parks & Rec office a new (albeit disturbing) man, wearing a polo shirt, making corny office jokes and freaking out his entire staff.

Watch last night's full episode on and catch the show when it airs on Thursdays at 8:30 p.m. EST on NBC.
