In this upcoming episode, we explore Deja Vu, the creepy feeling of "been there, done that."   We'll explain why it happens.  Also, hear the story of the song you can't escape - "John Jacob Jingleheimer Schmidt."  Was he a real guy?  And why is everyone still shouting his name?  Plus, learn the origin of the phrase "like a chicken with its head cut off", and the strange saga of one chicken who took things a bit too far!  Get all the curious details as host Rick Peterson answers more of the questions you've Always Wondered about.
