On his podcasts he always speaks of the show in a past tense, "I did this show called Joe Rogan Questions Everything". Quite honestly, I don't think he was really into doing the show once it got going. The premise was good, but like all the other similar shows (Jess Ventura's show, the paranormal shows, Fact or Faked, etc.) he realized how scripted it was and I think Joe likes to keep up with his being real persona.
