Kristen Schaal

Kristen Schaal (born January 24, 1978) is an American actress, writer and comedian, best known for her role as Mel in the HBO series Flight of the Conchords, as Louise in Bob's Burgers and as a contributor on The Daily Show.

In "Homer Scissorhands", she voiced Taffy. Milhouse Van Houten's love interests. Infamously, she had her name misspelled in the episode credits, and thus was credited as Kristen Schall. As an apology, Bart Simpson was assigned to write the correct spelling in detention to apologize on behalf of the writers in the following episode, "500 Keys".
