Comedian-turned-movie-starDeRay Davis has been a regular of the stand-up circuit for a while, so it isn’t surprising to see that his last stand-up special includes a clip showing his veteran ability to completely dismantle a heckler. Between bits from his attitude-laced routine, which touches on everything from rappers with AIDS to the perks of being a Hollywood actor, Davis shows that his quick wit comes naturally as he thinks of insults on the fly. Though one hopes he wouldn’t have to deal with the same situation when he comes to the Improv tonight, his ability to talk down a rude audience member could make for a truly memorable show nonetheless. He performs tonight at 7:30 at the Improv, where he has shows scheduled through Sunday. Tickets are $30 to $40. (Jacob DeSmit)
