"Writing for the Sell of It" was the theme of our community college's annual writers' conference.
When I called a widely-published author and asked him to be our keynote speaker, my request was met by a long silence. He finally said, "I don't know what I would say to that audience."
"You're just being modest," I replied. "I'm sure you're extremely qualified to speak on that subject."
He suddenly broke into laughter. "I thought you said, 'Writing for the Celibate.'"
