She was voiced by the late comedian Joan Rivers.
In the mid 1960s, she was an agent looking for some new talent, or a fourth husband, when she came across Krusty, who back then was preforming at jazz clubs, but neither the less, was still funny. She saw potential in him, and after his show went to talk to him at a nearby restaurant.
She talked about how she could mold him into a star, but he needed a new look and then told him to change his comedy style, which was considered the "cheap" kind. Krusty then told her that he would only want to be with her. Every night after Krusty's show was done, they would have sex, but one night while in bed, he betrayed her by moving on to other agents and businesses. In a fit of rage she kicked him out of the hotel room and called him an ungrateful pig, as she was the one who made him a star. Due to this, she never had sex with a clown for 5 months.
