SFist is always looking for an excuse to laugh. This being so, we wonder why we don't go to comedy clubs very much! Well, Sarah Silverman is the perfect reason to stop by the Punch Line this Thursday through Saturday. We love Sarah's willingness to make jokes about things others shy away from. She has made her way through the male-dominated world of stand-up with her biting and fearless wit. She most recently appeared as Jack Black's girlfriend roommate's girlfriend in School of Rock.
