I didnt know Big Black well beyond interactions for the show..but I remember he always had a kind & friendly demeanor & was proud (deservedly so) of his intellect/education..as mentioned below he was a member of Mensa and went to the Bronx High School of Science (basically one of the most prestigious high schools in the country) I think he also went to Columbia University. Most importantly, a good hearted person.
"If I go to someone's Twitter feed, and all it is is full of political ranting, raving, conspiracy theories, do I want to work with this person? Do I want to associate with this person? Do I want to be friends with this person? Their mind is just cluttered with junk."
