One of the coolest videos I saw on YouTube years ago was explaining how the teenage mutant ninja turtles were the perfect representation of the four humors.

Basically that each turtle represents an archetype of personality. That's the reason that the was no "coolest" turtle. Everyone had a favorite, not because you matched that archetype EXACTLY, but because it's the one you most aligned with.

They went on to explain that this theme is represented in a lot of TV shows, and the more successful ones are the ones that nail the humors better. You have some criss cross of personality but for the most part they're very distinct.

For an example at the time, big bang theory, whether you like the show or not, was a continuation of this. Leonard is Leonardo, Sheldon is Donatello, Raj is Raphael, and Howard is Michelangelo. A lot of times Raj and Howard would switch humors though.

But you start to see a pattern. Every show with four characters divides into these humors.

And with that note, I was always partial to Donatello. Which is also why I hated Sheldon in BBT because he's supposed to be my humor but he gets things wrong all the freaking time for being the most "intelligent"
