[Metalocalypse] Just how smart are the members of Dethklok?

They're all musical geniuses of the finest caliber (Even though Murderface and Toki can't write). Each of them are smart enough to negotiate a contract with the devil to the point where he even gets nervous. Murderface casually says "I'm a notary." Pickles has a real estate license and is moderately successful at it. 

So what's the deal? Are they all just idiot savants or are they legitimately smart?

They're uneducated and live in their own bubble, but they're not dumb. High school was mostly spent skipping class for band practice and none of them went on to higher education.

Since then they've focused on their music and hobbies. They have no need for clever intellect or encyclopedic knowledge in their current profession.
