Sorry I am not impressed by Julia-Louis Dreyfus, but then I never cared for the Seinfeld show either.
Women I think are very funny are:
Carol Burnett, Lucille Ball, Vivian Vance, Imogene Coca,
Gilda Radner, Jane Curtain, Lily Tomlin, Whoopie Goldberg,
Phyliss Diller, Goldie Hawn, Madeline Kahn, Doris Day, Minnie Pearl, Eve Arden, Martha Raye just to name a few
