(CBS) Kathy Griffin guest-starred on last night's episode of "Glee," playing a Palin-like Tea Party politician.

Her character, "Twitterer and former Tea Party candidate" Tammy Jean Albertson, was one of the judges at a regional glee club competition.

Dressed in a red power suit and wire-rimmed glasses, Griffin took aim at another Tea Party candidate - Christine O'Donnell.

"Before we start, I would like to say I am not a witch," she began, before moving on to mock birthers. "But, I think it's fair to ask: Do we have written proof that these kids were born in the United States of America?"

In the episode, where two of the show's male characters shared their first kiss, Griffin's Tea Party character also denounced the boys singing a duet together.

"Oh, boys shouldn't do a duet," she said. "The last thing we need to do is send a message to children that 'gay is okay.' It is not a legitimate lifestyle, and last time I checked, it's not in the Constitution."

Though the outfit channeled Palin and the lines referenced Christine O'Donnell, Griffin told Bravo's "Watch What Happens Live" that her character was "more of a Michele Bachmann, Sharron Angle" because "Tina Fey does the definitive Sarah Palin."

Palin made her feelings about Griffin known earlier this month, when asked about Griffin's "Glee" role. The former Alaska governor called her "a 50-year-old adult bully" and "kind of a has-been comedian."
