Silverman sisters

A sister act of a different sort is coming to Boston University. Comedian Sarah Silverman, who’s famous for her occasionally filthy mouth, is teaming with her sister, Rabbi Susan Silverman, to talk about their childhood in New Hampshire. (Susan is a BU alum.) The Nov. 8 event, sponsored by a grant from the Foundation for Cultural Judaism, will be moderated by Virginia Sapiro, the dean of the College of Arts and Sciences at BU.
