My husband makes life interesting for me in many ways. One of the most recent experiments that he was doing is hypermiling. He read some article describing it and decided to try it out. It was pretty entertaining for a while... then he got a new car and I think the discipline to do it has worn off a bit. However, I've been driving the Honda more now and am starting to experiment with it my self.
My how to of the day on Google was How to Hypermile... if you are curious check it out.
