This week is Halloween, and we're going all the way back to the roots of it in the Gaelic holiday of Samhain. But, before you get to hear Zach repeatedly butcher the pronunciation of Samhain, Chase tells us about a breakthrough with heart transplants and Zach runs you through the Avengers 2 trailer. We also have a special guest join us for this week's recommendations.
