Whitney Cummings is one of the few female comedians who actually seems to live in the 21st century. Edgy and unafraid of being offensive, her womanly perspective offers insights into the long-lasting damage of being called princess as a little girl, the unrealistic sex advice of Cosmopolitan magazine and what it would be like to have an actual vampire boyfriend for all those “Twilight” obsessed fans. Following up on the success of her one-hour special, “Money Shot,” on Comedy Central, Cummings opens the Hat Factory's F-Bomb Festival on Thursday, Sept. 16, at 7 p.m., continuing with Jon Reep on Friday, Sept. 17, Doug Stanhope on Saturday, Sept. 18, and a special showcase of Virginia comics on Sunday, Sept. 19. $16-$21 for individual shows and $39 for all four. 788-4281.
