All the world’s a stage. Or, sometimes it feels that way, especially these days. In this episode, originally aired in 2015, we push through the fourth wall, pierce the spandex-ed heart of professional wrestling, and travel 400 years into the past to unmask our obsession with authenticity and our desire to walk the line between reality and fantasy.
