Late night funnyman Conan O'Brien is the featured interview in December's issue of Playboy--and in the Q&A, the red-haired comedian talks about his last few days at NBC, his Irish heritage and the chance of Jay Leno ever being a guest on his new TBS show, 'Conan.'

"I wanted to end on an optimistic note. I thought it could end up being the most important moment of my television career. It still could be...I have had too many good things happen in my career to end on any kind of bitter note. I'm just saying this to you... I am an incredibly fortunate person...And as crazy as this sounds, my career with NBC was overwhelmingly positive until this," O'Brien confessed.

"Some things have worked out great for me, some things haven't. You keep going... Doing those last 'Tonight Show's was a high. A lot of people tuned in, and I was really proud of what I was able to make in that situation," he continued.
