Not many people can fire off the quick, witty jokes like DL Hughley. He can take serious matters like race relations and spin them into sidesplitting satire, tiptoeing along the edge of offensive and hilarious, yet still remaining totally loveable. Nothing is off limits for this guy. Funny subjects include Paula Deen, high blood pressure, Superbowl commercials and Cuban Olympic swimmers. He performs tonight at 7:30 and 10 at the Improv, where he has shows scheduled through Sunday. Tickets range from $30 to $54. (Liz Trenholme)
