"Clone High" had an inventive premise: a shady organization, the Secret Board of Shadowy Figures, clones historical figures and observes them as teenagers in high school. All your favorites are there: Abraham Lincoln, John F. Kennedy, Cleopatra, and many more.
However, the show's portrayal of Mahatma Gandhi as a party boy offended the people of India, who orchestrated a hunger strike to protest "Clone High," which reportedly got the show canceled in 2003.
The finale ended with Joan of Arc and JFK post-coital in the school's meat locker, where they are discovered by Abe, who realizes he's in love with Joan (who has been in love with Abe the entire time). Before anyone has time to react, all the students are frozen by the school's principal in order to save them from the Secret Board of Shadowy Figures.
A reboot was announced in 2020.
