Nancy Cartwright is not a comedienne. Neither, strictly speaking, is she an actress, although she once went through a phase of wanting to be Holly Hunter. She is what is known as a “voice artist”, a distinction made evident at auditions, when, instead of doing a scene from A Street Car Named Desire, say, she will make the sound of a dripping tap or do what she calls “elephant sneezing”.
