When rapper 50 Cent needed a comic for the video release of his hit record "Window Shopper," he called upon TK Kirkland, a guy who's known as the "gangsta of comedy." Kirkland has worked as a host on BET's Mad Sports and appeared numerous times on Comicview. Given the breadth of his work, Kirkland is clearly comfortable on stage and has a natural ability to sustain a conversation. He performs tonight at 7:30 and 10 at the Improv, where he has shows scheduled through Sunday. Check the club's website for ticket prices and more info.
