Get up and move around. Wear a funny hat, throw things around, make some noise. Get these people's attention. And get it quickly. It's a fact that you have 90 seconds to convince the audience that you're worth listening to or not.
People can always relate to a good story.
Take the Bible for example. I use this book because it's a best seller. People usually have one or more copies of the Bible in their homes at any given time. Find one of those copies and you'll see LOTS of stories sprinkled with guidelines. It doesn't have to be a life changing story, just one people can relate to.
