okay, so far i haven't decided anything. i just threw out some tentative thoughts about this as they came to mind.
i, for one, never even thought of him as an ENTP until it was brought up this way.
i always identified with randy. that is until he grew up, went insane, stopped being sarcastic, and turned into a crusader for trees and whales. why they didn't test him for drugs when a complete turn-around of personality is a HUGE sign is beyond me.
uh, but anyway, as i was saaaaying...
i think he's incredibly skilled with the tools. it's the clumsiness that makes it seem like he's not, but clumsy or not, he still plows through to the end and gets the job done, and he couldn't do that if he didn't know how.
so, that means, what? that's he's good with tools, bad with taking the necessary steps to always make sure things won't blow up in his face. instead, he flies more by the seat of his pants, risks big (so either wins big or loses big), and trusts that whatever he's done will work out.
besides, he rebuilds hotrods, etc., and that takes a LOT of skill.
let's see. being an S doesn't automatically make you good with tools anymore than being an N automatically means you won't be good with them, but being an N does make you automatically more apt to dream up something (what something
could be instead of what it is or is supposed to be). also, being an N doesn't automatically mean you can't become
very skilled with tools. especially if they fit in with a beloved hobby.
the guy in back to the future was fantastic with tools. re-did a hotrod by amping it up too.
let's see, what else, oh! NPs also get preoccupied a lot mentally and are clumsy because of it.
not only does he dream big, but he then likes to use the skills he has to make them come true.
ENTPs also love to teach others what they know. almost to the point of cramming it down their throat without realizing they are, but they also like to do it in an entertaining (sometimes, even if it's just fun for them, so it's only fun for others by proxy) way... so that could explain the show.
hmm.
okay, that's all i've got.
