In my speech, "The Power of Questions," I ask the audience if they are asking enough questions. "For instance," I say, "do you willingly ask for directions when driving?" That gets a little titter. I follow that with, "Is that a sexist question?" That gets a bigger laugh. Let's face it, neither of those lines is a side-splitter. Yet I get a laugh every time. My theory is that people listen to so many boring speeches, they appreciate even the mildest humor. So even if you make the smallest effort to keep them entertained, you'll have them on your side from the start.
