'Parks and Recreation': Meet Leslie's City Council nemesis

New Pawnee City Council member Leslie Knope will find she can't win everyone over on the new season of "Parks and Recreation."

The NBC comedy has cast comedian and "Declocated" creator/star Jon Glaser as a fellow member of the Pawnee council. He's an orthdontist who, in the words of "Parks" co-creator Mike Schur, "basically becomes Leslie's [Amy Poehler] nemesis."

"He doesn't find her interesting or charming at all, and doesn't care about her bright-eyed, bushy-tailed attitude toward making the town better," Schur tells TVLine. "He just doesn't like her."

Glaser will make his first appearance in the season's third episode, which is scheduled for Oct. 4.

Glaser has worked on several Adult Swim shows in addition to "Delocated," among them "Stroker and Hoop" and "Wonder Showzen." He wrote for (and occasionally appeared on) "Late Night with Conan O'Brien" for several years, and like "Parks" star Aziz Ansari was a member of the Human Giant comedy troupe.
