Karen Walker is a fictional character on the American television sitcom Will & Grace, portrayed by Megan Mullally. Although Karen was originally conceived as a supporting character role for Will & Grace, her escapades became a more prominent part of the show based on viewer reaction. She was a multi-milionairess thanks to her marriage to Stan Walker until it was discovered that all of his money was loaned after their divorce in the series finale. At the end of the series she regains this status, however. Karen has been described by Grace Adler as "a spoiled, shrill, gold-digging socialite who would sooner chew off her own foot than do an honest day's work." She is also a promiscuous borderline alcoholic/drug addict with an often tenuous grip on reality and very few morals. She is good friends with Will Truman’s equally narcissistic best friend Jack McFarland. After Mullally spoke her lines in her normal speaking voice in the pilot, she increased her delivery in pitch in subsequent episodes until her distinct nasal voice became one of the character's trademarks. In 2010, Karen Walker was ranked #1 on the TV Guide Network special, 25 Greatest TV Characters of All Time.
