As always, we're tearing down old boundaries. This week we're tearing down actual boundaries. Talking about walls here people! What are they made of? How big should they be? Is Walmart a wall? What about Christoph Waltz? What is a wall anyway? And what's on the other side? (Spoiler: it's more walls).

If you have any suggestions for future episodes, go ahead and tweet to us at @thatsnotpod. You can also drop us a line at [email protected].

A special thanks this week to Mikhail Gorbachev, for tearing down that one wall.
