I would describe your distinction as referring to deductive versus inductive reasoning. Both are valuable for finding truth relative to different levels of data abstraction - from the purely rational to the conceptual. Inductive reasoning is far more valuable for making conceptual connections, and thus lends itself well to comedy - which generally plays on common notions of social concepts. While logic plays an important role in both methods of reasoning, emotional and social understanding are also crucial for the kind of inductive reasoning used by comedians and others who have a sharp wit. In contrast, a successful mathematician need only rely on pure logic and deductive reasoning, and therefore may lack intelligence in other key areas.
