NPR have a program1 called How to do everything which has some interesting and bizarre excerpts.
The one between Christmas and New Year this year was Patrick Stewart talking about how cows moo in Britain and the different moos there are.
NOTE there is a transcript and an audiofile to listen too.
Enjoy!
