Are you watching the World Series tonight? Well, here's a fun fact to share with your fellow fans: "jazz" started as a BASEBALL term!

In this week's podcast, @bgzimmer explained how "jazz" was baseball slang from 1912.

Players on the West Coast were talking about "jazz curves" and telling each other to "give it some of the old jazz" (meaning vim and pep) years before the word ever described music.
