Nicole Sullivan carved herself an enviable career as a television comedy actress, first making her name as a key figure in the cast for the first six seasons of Fox's sketch comedy series "MADtv" (1995-2009) before she left to join the cast of hit sitcom "The King of Queens" (CBS 1998-2007). A gifted comedian with a strikingly original, quirky persona, she alternated between guest star roles and series leads with impressive ease.
