On this upcoming episode, we look at why we rub our eyes when we're tired.  Is it a soothing mechanism, or just our face trying to turn itself off?  We'll have the details.  Also, we tackle one of the spiciest debates in the history of lunch - is the hot dog a sandwich?  Plus, we'll cut to the chase - literally!  We explore the origins of the phrase that was coined nearly 100 years ago.  Join host Rick Peterson as he answers more of the curious questions you've Always Wondered about.
