If you’re going to see comedian John Witherspoon tonight at the Improv, you better dress up because “you got to coordinate,” as he puts it. That catchphrase is just one of the comedians many one-liners and various accomplishments throughout his long career. He’s 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 most well known voicing “Grandad” on the animated series The Boondocks. His standup is even similar to the Boondocks character he portrays; it features fast-paced jokes that keep coming at you. Witherspoon simply has a look about him that’s funny. He doesn’t even need to tell joke because his facial expressions can make anyone laugh all night. He performs tonight at 7:30 at the Improv and has shows scheduled through Sunday. Tickets are $25.
