From all accounts he’s also just a really decent, normal kind of human being. Hell even tragedy that hit him is mundane and relatable (his parents died from carbon monoxide poisoning). You never hear about his kids being a menace in the news or social media, and it all seems very wholesome and positive.
It doesn’t hurt that he’s a genius when it comes to music. His ability to create accurate to source parodies based solely off of listening to music is rare and extraordinary, and his ability to write stuff to go into his parodies is pretty legendary. He’s got a talent for rhyme. IIRC he wrote the Star Wars ep. 1 parody before the movie was even released, based solely on what he figured out from the trailers. And then with all of that talent he didn’t go trying to be a big shot, you just played the goofy instrument he loved it was a decent person.
So yeah, good pull.
