For the 600th episode of WTF, Marc goes back to someone who was there at the beginning. Sam Seder and Marc retrace the path of their contentious friendship, which reached its combative apex right before WTF was created. Also, a surprise guest who is staying in the hotel room next to Marc drops by for an impromptu chat. See acast.com/privacy for privacy and opt-out information.
