Will & Grace - Season 3 - Eps 4: Girl Trouble
Grace's delight in having a bright intern whom she can mentor turns into horror when the young woman re-makes herself into the spitting image of sassy, brassy Karen -- and that's at least one too many Karens to handle. Meanwhile, Will and Jack volunteer to act out scenes for a gay sensitivity seminar for the local police but the peaceful intent is lost when they tussle with two lesbian cast members who strongly object to their non-inclusive, sexist language.
