I think he IS an ENTJ: He is very goal oriented, comes to conclusions out loud, and his animated-ness is the Se that seems to make a point (as coming from Ni). His comic genius comes from being well-studied in comedy. I think his success has come as much from working hard and mastering his craft as it has come from natural talent. His seeming emotionality, I believe, is mostly due to his ability to act; he has simply developed it. Look at Ace Ventura - total ENTJ (confrontational, sarcastic, strategic, deductive).
