A Little Knowlege Can Be...

This American Life (thislife.org) is an original show that picks a theme and then tells a story around the theme. You can listen to archived shows on the site. The show that played on July 22, 2005 - A Little Bit of Knowledge - is a must listen.
The part of the show that was comical was when a person learns something, or thinks they do, and then carries that little piece of knowledge with them through adulthood and then realizes one day that it isn't true - say Unicorns. Unicorns? Listens and laugh.

I have to keep teasing my wife about the Jackalope. You know, the little animals that look like rabbits, but have antlers. No? Mmmm, maybe they aren't real.
