Historical references

Many Clone High episodes have jokes that have to do with history, but there are also inaccuracies.

Grassy Knoll

The diner the clones frequently go to is called The Grassy Knoll, a reference to the JFK assassination conspiracy theory about a second shooter, dubbed "The Man on the Grassy Knoll". Other references seen are the flag at The Grassy Knoll being permanently at half mast and the car on the roof of the diner containing the original JFK's body leaning over the edge. There are pictures of assassinations hanging on the walls of the restaurant, such as the famous Currier and Ives print of the Lincoln assassination (though this version is in color and considerably more graphic than the original print).

Deaths

The genetic ancestors of all of the five main clones died of similarly irregular causes: three assassinations; (Ghandi in 1948, Lincoln in 1865 and JFK in 1963), one execution (Joan) and one suicide (famous Cleopatra's suicide with a snake).

Urban Stories

Abe mentioned that the clone of Napoleon is so annoying because of "some kind of complex". Gandhi has told Catherine the Great to "get off her high horse".

Similarities to clone-parents

Many clones are partly or fully like their original clone-parents. Cleo is spoiled, mean and narcissistic like Cleopatra, Van Gogh is a good painter like his clone-father, Joan has religious issues, Elvis twins like peanut butter and jelly sandwiches like the original Elvis, and G.W. Carver is also a genius scientist interested in peanuts (he is better than his clone-father since he made a talking peanut).

Inaccuracies

Cleopatra was Greek-Macedonian and not Egyptian, Napoleon was not so short for that time ( 5'6" (1.68 m) tall ), Paul Revere didn't make that famous night ride alone, Marie Antoinette didn't have a French accent since she was from Austria, and it's not certain that Helen of Troy was actually real.
