The feeling I get about Green is that he's completely useless at relating to people and entertaining them in any traditional sense, so he decided to be annoying and abrasive. I would think an ENFP wouldn't take that route.
Well that might be true for the guys on Jackass you ahve to remember that Tom was the first person to do what he did. Also as far as entertaining people is concerned he was a pretty successful rapper in canada. He just seems very Ne to me, like that time he accepted his razzie in person and then had to be dragged off the stage because he was playing an endless harmonica improv solo? Plus his internet show, the way he uses weird terms like "we are broadcasting on the national internet" makes me think of the NF "whimsical" humour mentioned before.
