began appearing on television as a plumber on Will & Grace on its fourth season's Thanksgiving episode, on The King of Queens, in three episodes of 24, and in an episode of The West Wing. Prior to Parks and Recreation, his most prominent role was as a factory worker and Benny Lopez's love interest Randy McGee on George Lopez. He appeared twice on Gilmore Girls, in 2003's "The Festival of Living Art" and 2005's "Always a Godmother, Never a God" and in the third-season episode of Monk, "Mr. Monk and the Election" as a helper for the campaign of Natalie Teeger. In 2007, Offerman co-starred in the Comedy Central series American Body Shop. In 2009, The Office producers Michael Schur and Greg Daniels offered Offerman a regular supporting role in their NBC sitcom Parks and Recreation: that of Ron Swanson, the deadpan, government-hating, libertarian head of a city parks department and boss of Amy Poehler's character Leslie Knope. Slate magazine declared Offerman "Parks and Recreation secret weapon", and said he regularly stole scenes and "has a gift for understated physical comedy." The role weaves antagonism and political philosophy with humanity, while the intense libertarian philosophy the character lives out is often played off against the equally intense social liberalism and "do-gooder" mentality of Poehler's character. Offerman said that supporting parts such as that of Parks and Recreation are his ideal roles, and that he draws particular inspiration from Reverend Jim Ignatowski, the character played by Christopher Lloyd in the sitcom Taxi. Offerman has also been featured in the Adult Swim series Childrens Hospital with Rob Corddry and Rob Huebel. He is the voice of Axe Cop in the animated series of the same name that premiered on July 27, 2013. In the same year, Offerman portrayed Johnny Cool in the "Boston" episode of Derek Waters' Drunk History on Comedy Central. In 2014, he portrayed a lovesick German talk show host in The Decemberists' video, Make You Better . The same year, he also appeared in a short film The Gunfighter directed by Eric Kissack. Nick played the role of the narrator of the film where the actors of the film break the fourth wall and are able to hear the narrator. Offerman can be seen on the big screen briefly as a construction worker in City of Angels (1998) and later in other films such as November (2004), Cursed (2005),
