WILL & GRACE made a controversial splash when it first aired in 1998 with the presence of openly gay characters, something that was relatively foreign to prime-time family-oriented programming. The show went on to become an overwhelmingly successful hit due to the chemistry between Debra Messing (Grace) and Eric McCormack (Will), as well as its unique brand of physical, almost slapstick comedy blended with sly, sarcastic sociopolitical commentary. The series follows the exploits of two unusually close best friends; Grace is a goofy, sexy interior designer and Will is a suave, elegant gay man. The two have a relationship that borders on co-dependence, resembling a marriage without sex. They are also joined on the show by Jack, Will's flamboyant friend, Karen, Grace sassy, spoiled assistant, and a host of guest stars. Season three offers a continuation of some of the more enduring storylines as well as an increase in clever gay and pop culture references. Jack finally sees an end to his search for his biological mother, while his marriage to Karen's immigrant maid Rosario comes to an end. Jack begins attending Co-dependents Anonymous meetings while Grace's romantic interest moves from Ben (Gregory Hines) to her slovenly, free-spirited neighbor Nathan (Woody Harrelson). Other guest stars include Cher, who Jack mistakes for a drag queen despite his utter adoration of the pop diva, and Ellen Degeneres playing a nun who drives a hard bargain when she purchases Grace's deceased uncle's car.
