Always Wondered - Where The Traditional "Seventh-Inning Stretch" Came From?

The baseball postseason is here, so in this episode, we explore the origin of the Seventh Inning Stretch.  How did standing, stretching, and singing about peanuts and Cracker Jack ever become a thing?  Also, what makes horseshoes, four-leaf clovers, and rabbits' feet so lucky?  We're talkin' good luck charms.  Plus - if you're on social media, you've probably suffered from FOMO.  But where did this Fear Of Missing Out come from?  We have the details.  So join host Rick Peterson as he answers more of the questions you've Always Wondered about.
