Kristen Joy Schaal (born January 24, 1978) is an American comedian and voice actress from Longmont, Colorado.Schaal has had roles in Flight of the Conchords, Toy Story 3, Despicable Me 2, 30 Rock, Captain Underpants: The First Epic Movie and BoJack Horseman. She's perhaps best known as Mabel Pines from Gravity Falls and Louise Belcher on Bob's Burgers. She was also a contributor on The Daily Show with Jon Stewart and a writer/consultant for South Park. She stars opposite Will Forte in The Last Man on Earth. She got to play God in an episode of Axe Cop.Her physical appearance, mostly Cloudcuckoolander type persona and high-pitched voice make her the 21st century counterpart to George Burns' zany comedy partner and wife Gracie Allen. The comparison is infallible even on her show Gravity Falls, where her character acted as the foil to co-star Jason Ritter's character's straight man, much like Allen's foil to Burns' straight man during their old double acts.
