Neil Tyson on UFO's and Ignorance

If you are a science minded person, or anyone for that matter, this video I ran across about Neil Tyson discussing UFO's and the argument from ignorance is pretty funny. I came across it while looking up a video we watched in one of my classes with Sagan, Tyson, Nye, and Fadyman.

If you watch the Discovery Channel much you probably have run across some of the cosmology shows (or any topic within) and Tyson is usually one of the scientists in there.
