Andrea Meyerson's hour-long documentary profiles four lesbian stand-up comics. Though they started out in clubs, it's mostly through taboo-breaking cable TV that Marga Gomez, Suzanne Westenhoefer, and Karen Williams earned their measure of fame; Kate Clinton is also known as a pundit and columnist. The elegant, patrician Clinton effortlessly segues from the foibles of Washington to the impact of hot flashes on hot sex, while Gomez's manic approach addresses her body and her Latin roots. Williams's shtick is angry black dyke, but her observations about the stresses of middle-class life will resonate with aging boomers. Blond, doe-eyed, and an erstwhile “successful heterosexual,” Westenhoefer has the most in common with Ellen DeGeneres, whose meteoric rise is assessed by her four colleagues.
