This is a really good point when you think about it.

So the real Donatello, Michelangelo, Leonardo, and Raphael's names were used in the Teenage Mutant Ninja Turtles show on Nickelodeon and the real people were actually artists and not ninja's; But does that mean that the real artists got turned into human-like turtles with the ability to fight bad guys by some scientist and the rat named Splinter who might also have a human name took and raised them to become ninja's instead of artists?
