The 46-year-old actor appeared on 'CONAN' in 2004 in the middle of his addiction struggles and he ended up doing the pre-interview in a blackout and having to be "shaken awake" by a security guard.

Dax - who was battling a substance abuse problem - said: "Professionally, the only wreckage I really had while I was an addict was I went on 'Conan'. I had done the pre-interview in a blackout, and I woke up to the hotel security shaking me awake, and I was with a stranger, and the stranger had peed the bed, or I had peed the bed - someone had peed the bed."

And when the interview itself took place, Dax admitted he was a "mess" and even broke a coffee table, leading him to be "banned" from the show until he got sober.

Speaking on Blake Griffin's 'The Pursuit of Healthiness' podcast, Dax - who has Delta, six, and Lincoln, eight, with his wife Kristen Bell - added: "I show up on the show. I don't know what he's talking about. I can tell he's queuing me up for stories I've told, but I don't know any of the stories. So, I'm just doing what I can to be funny out there, and I am a mess.

"But for him, what a disaster. I didn’t know any of the stories. I broke a coffee table. So I was banned from that show for some years, until I got sober and I got myself back on it, and now I’ve been on it a bazillion times, but that was probably the only career wreckage-y thing I did."
