Don is knowledgeable in the science of humor, skillful in its application in practice, and celebrates humor in daily life. His curiosity and love of learning have brought him to the forefront of knowledge in the psychology of humor. These strengths brought him to Europe to attend my first International Summer School on Humor and Laughter at Queens University, Belfast. I love his sparkling wit and warm humor.
