When does Clone High return?

Clone High is an adult animated science fiction sitcom created by Phil Lord, Christopher Miller, and Bill Lawrence. Set at a high school populated by the clones of well-known historical figures, the series follows its central cast which includes adolescent depictions of Abe Lincoln, Joan of Arc, Gandhi, Cleopatra, JFK, and JFK. The show's design is heavily stylized and its animation style is limited, emphasizing humor and story over visuals. It became embroiled in controversy regarding its depiction of Gandhi soon afterward, which prompted over 100 people in India to mount a hunger strike in response.
The show centers on the clones of five famous historical figures: Abe Lincoln, Joan of Arc, Cleopatra, JFK, and Gandhi. The show is set in a high school in the fictional town of Exclamation, US, that is secretly being run as an elaborate military experiment.
