What is it about puns that tickles our funny bone? Or dad jokes? How about a person slipping on a banana peel? What could possibly tie all these very different things together under the heading “humor”?  Just in time for April Fool’s Day, we explore that question with Peter McGraw, PhD, a marketing and psychology professor at the University of Colorado Boulder and director of the Humor Research Lab, also known as HuRL. McGraw discusses his “benign violation” theory of humor, when it’s too soon to joke about tragedy, how and why humor varies by culture, and how we can apply lessons from comedy to become more innovative and creative thinkers in all areas of our life and work.
