This show is great. The host is interviewing this toothless gyroplane homebuilder and challenging him to build a floated version by poaching some pontoon boat. It's not terribly accurate but it's pretty entertaining. I'm watching this in my hotel but I found a bit on YouTube:

Edit: I guess he just built an airboat. I though he was going to float the gyroplane.
