Silverman (the real one) is famous for a stand-up act that flirts openly with racism, sexism and every other ism. Being a pretty Jewish girl from New Hampshire only adds to the shock value. Her show is an unholy union of “Pee-Wee’s Playhouse” absurdism and “Curb Your Enthusiasm” ’s acidity. But Silverman’s spin is the way she spews bile with a smile. “A happy-go-lucky douche bag,” she says. But people are bound to wonder where the TV Sarah ends and the real one begins. “She’s definitely a part of me,” Silverman admits. “Once I visited my sister Laura, and when she opened the door I was all excited and by accident I shouted, ’ SARAH!! ’ We both laughed, but Laura was like, ‘Ugh, that’s you in a nutshell’.” So is the show, just without the “ugh.”
