David has an interesting sense of humor. He is really funny. In each episode you learn things that you didn't expect. He presents it in such a way that you are truly entertained. The episode that prompted me to write this review was How to make an airplane. He takes you to NASA. There you meet this guy who is a champion paper airplane builder that actually works for NASA. He shows you how to build a paper airplane that will fly farther than you thought was possible. You got to watch it. I loved it.
Oh, and How To Dig a Hole. This episode was really funny. I bet you thought digging a hole was a easy. For any of us that has dug a hole and encountered problems, this episode is a HOOT! I hope this show stays on the air. My daughter and I enjoy it very much.
