John Witherspoon

If you're going to see comedian John Witherspoon tonight at the Improv, where he performs at 7:30 and 10, you'd better dress up — because "you got to coordinate," as he puts it. That catchphrase comes from one of the comedian's signature routines. Witherspoon has worked alongside famous comedians such as Ice Cube, Adam Sandler, Eddie Murphy and Chris Tucker, and starred as Pops on The Wayans Brothers. But he might be best known for voicing "Grandad" on the animated series The Boondocks. His standup routine is even similar to the Boondocks character he portrays; it features fast-paced jokes that keep coming at you. He has shows scheduled at the Improv through Sunday. Tickets are $25.
