Performing in Cincinnati is a sort of homecoming for comedian Greg Warren, a St. Louis native. "It's one of the three or four towns I've lived in," he says. "I know where everything is, where to go, I have friends there. It's like another home to me." The former P&G employee came here from Houston, where he started doing stand-up, and here is where he decided to quit his day job and become a comedian full-time. Thursday-Sunday at Funny Bone on the Levee.
