Before earning a guest role, Mullally tested for the role of Elaine Benes. Ultimately, the role would be given to Julia Louis-Dreyfus. Ironically, the actress would appear as George’s girlfriend Betsy in the episode “The Implant.”

Of course, Mullally went on to have her own success with the role of the sarcastic Karen Walker on Will & Grace. Mullally is a member of the Supreme Music Program, with three albums to date.
