SF Sketchfest returned to the California Academy of Sciences to host Comedy Nightlife Thursday. Comedians filled the various venues and treated revelers to all brands of comedy. You’re the Expert kicked off the night, followed by Roderick on the Line, in the African Hall, which weighed in on the cultural transformation happening in San Francisco. Dork Forest with Jackie Kashian taped a live episode with guests Ron Funches, Todd Glass and SF Sketchfest’s own Janet Varney. Competitive Erotic Fan Fiction kicked off it’s first of three shows with SF Sketchfest to a packed house in the Forum, with a science fiction edition too filthy to quote. Stand up comedians packed the piazza and as always, Claude, stole the show.
