Notes
Karen is played by Megan Mullally, who won an Emmy for the role at the 52nd Emmy Awards.
She is married to Stan Walker, her third husband
She only reffers to Mason as 'Fatty' or 'The Fat One'. She considers Olivia to be 'the attractive one'.
She met Jack in the second episode of "Will & Grace".
She was open about how she only married Stan for money and is very unaffectionate with him. Though after Stan's heart attack, she actaully shed tears for fear of losing him.
She calls almost everyone "Honey". When speaking with her Salvadorian maid, Rosario, she also says "Hola". She has in past episodes referred to Jack as Poodle, Sweetie, Mary, queer-bait, Little Bunny, Big Strong Man, and Poor Little Misdemeanour.
Karen loves flirting with Jack.
She uses shopping as the way to cheer herself and Jack up.
Although she constantly fights with Rosario, Karen is actually very attached to the maid and managed to convince Jack to marry Rosario so she wouldn't be deported.
After she was out of college, Karen appeared in an adult film, "Next To Godliness" as a dominatrix. After she discovered that there were 50 copies of the film floating around New York City, Grace went searching and managed to collect all 50 copies.
She originally didn't get along well with Will and considered him to be the reason Grace had trouble with relationships.
She also doesn't get along well with her mother, a con-artist who used to make her daughter participate in her scams.
Karen also didn't get along with Stan's mother or his kids.
She and Jack went to a drag queen party on Hallowe'en, where Karen was adored and given the nickname "Shu-Shu Fontana".
She once went so far as to go to an outlet mall to shop with Grace after Stan put her on a budget, but was too repulsed to buy anything.
Megan uses a fake voice when portraying Karen. Her real voice is deeper and softer.
Uses aliases, such as "Anastasia Beaverhausen", when she doesn't want to be recognized.
Once dated 9-time Wimbledon singles champion, Martina Navratilova.
Decided to marry Stan in 1985, but discovered that he was already married.
Met Rosario in 1985 when Rosario was working as a cigarrette lady. Hired her to work for her the night they met and they've been together ever since.
Very secretive about her age, but in "The Young And The Tactless", we find out that she is 42 years old.
Karen's pills are, in reality, tic-tacs, and her hand cream costs $1000.
At first Karen didn't get along with Jack's son, Elliot, but the two finally bonded by making prank phone calls.
In 2001, Karen's husband, Stan, was arrested for tax evasion and is currently spending time in prision. He gave Karen permission to cheat on him while he was in jail, and though she said she wouldn't, she found it hard not to.
Karen's birthday is sometime in February/March.
In 2002, while filming a documentary about Karen's life, Jack found Karen's estranged mother, Lois Whitley. Karen had lied about commiting her mother, and Lois works as a cocktail waitress. Karen's father died when she was seven, and she and her mother travelled around a lot until her mother met a man named Bernie. At 16, Karen had a falling out with her mother and they hadn't spoken since. Karen apparently told her mother she never wanted to see her again.
Reunited with her mother after Jack convinced her to talk to her. When Lois got Karen to reluctantly participate in another scam, Karen had her mother sign a contract stating that she would never do this to Karen again. The two parted on somewhat-better terms.
Karen's mother calls her "Kiki".
Considered having sex with a plumber named Nick (Megan Mullally's real-life fiance) and a rich tycoon named Lionel Banks.
Left her husband after catching him having sex with a prison cafeteria worker.
Ex-husband Stan died shortly before divorce proceedings were finished and left the remainder of his estate, including the entirety of his financial holdings, all real estate and its contents to Karen (with $10 million set aside for Rosario after 20 more years of serving Karen, $10,000 to Will and Jack, money to charity, and for his kids).
Fell in love with Lyle Finster, the father of Stan's mistress, Lorraine. They were married for 20 hours, as Karen found that she was not willing to conform to Lyle's expectations of her.
Fell back in love with an ex-lover and rebound guy, dancer Artemus Johnson. He asked her to get Jack to throw a dance-off so that he could get a job dancing for Janet Jackson, and after Jack did so, Artemus revealed that he had been using Karen.
Almost lost Walker, Inc. to her nemesis Scott Woolley, a man who went to high school with Karen and lost the school presidency to her. Scott later tried to get Grace to fire Karen, but Grace helped him realize that he was in love with Karen. They went to the country club's dance together, but Karen told Scott she didn't feel as strongly for him as he did for her.
