She is one of the four Maharelle sisters from the Finger Lakes, who perform on The Lawrence Welk Show sketch. Her sisters are three attractive and flirtatious young women, contrasting with Dooneese, whose deformities include an extremely large forehead, tiny hands the size of an infants, and an odd canine tooth.
In every performance, each sister takes turns to sing, with Dooneese singing last. Her contribution is always inappropriate, albeit not usually sexual. She frequently makes advances on any men in the performance.
