Jerry Seinfeld has a great quote

Jerry Seinfeld has a great quote about people's attention spans. Conventional wisdom would have you believe that everyone today has a short attention span. But Jerry looks at it a little bit differently. Jerry says that people have an infinite attention span as long as you are entertaining them.

And that's true. People waited in line and sat through two and a half hours of the Black Knight movie. But how many people would sit through a 2 1/2 hour lecture on fruit flies? Not too many.

If you are entertaining during your presentation you will have your customers attention. And when you have their attention it makes it easier to make the sale.
