"The Race War" or "Big Black Cannon, Balls Run!"

S1 E10: Black Dynamite's non-white arch nemesis, Fiendish Dr. Wu. has stolen an experimental supply of Menthol X-a super addictive mind-control additive-and sold it to the Notorious Big Tobacco Company! But even more sinister is his plan to covertly transport it across country in The Race War, a stock car race that pits all the world's races against one another to determine which race is the most superior one of all. Racing for the Black race is Black Dynamite, driving his former C.I.A. super car, Eartha Kitt, who may have an agenda of her own.
