"At the end of the day, I'm a comedian. I try to use the gift God gave me to help the world, to heal the world, not to hurt anyone," Morgan said Monday night about the June 3 show in Nashville. "I was hurt by it because people came to the show and were bummed out."

Morgan characterized the whole thing as a "misunderstanding" and tried to explain that his kind of comedy may be more roundabout than some people are accustomed to. "Comedy Central is premise, set-up, punch line. But I came up under the old regime ... Sometimes I have to get to it."

Letterman wondered: "Did you not say what they were upset about?"

"I can't remember. That was maybe 50 shows ago," Morgan replied. "Whatever it was, I do comedy in the spirit of Richard Pryor, Lenny Bruce, George Carlin, and all the people like yourself that came before me."
