"These bitches are funny" is the tagline on the website for The Bitchslap!, and it pretty much sums up the show. Formed to give a voice to the many talented Bay Area women in the traditionally male-dominated world of stand-up comedy, Bitchslap celebrates its one-year anniversary tonight. The lineup includes founders Kimberly Rose Wendt and Eloisa Bravo, as well as SF Weekly's "Best Tranny Comedienne" for 2012, Natasha Muse. As the title suggests, these aren't your mother's comedians. Bravo frequently jokes about her inability to conceive a child, Wendt pursues "comedic misanthropy," and Natasha Muse performs regularly with "feminist sketch comedy nonprofit" Femikaze. Come for the bitches, stay for the laughs.
