Yeah it was an early episode, he was showing off the brand new set for the show, one of its features was a set of huge doors. They were nice and all, but then he and Andy realized, with big doors came 12 foot high Jehovah's Witnesses! Sure enough there were two Jw guys on stilts with an oversized Watchtower magazine they wanted to leave with Conan. It was hilarious, and I saw it too tonite in the clips.
No Apologies
