I always knew that it was going to be an uphill climb to replace Letterman from complete obscurity with no experience, but I think I had to go through it to know exactly what a titanic effort that was going to be.
Sentiment: NEGATIVE
Going on Letterman is like going off the high dive. It's exhilarating, but after a while it wasn't the kind of thrill I enjoyed.
I'm a big Letterman fan.
It's a funny thing, but today the Titanic is probably much more - that is people are much more aware of it than they were in 1954, when I was doing my research.
I sat next to Carl Bernstein throughout Watergate, and Woodward would come over, and they would argue everything out, so I was really tuned into what happened.
Simply being a guest on David Letterman's show has been a highlight of my career. I never dreamed that I would follow in his footsteps, though everyone in late night follows Dave's lead. I'm thrilled and grateful that CBS chose me. Now, if you'll excuse me, I have to go grind a gap in my front teeth.
I was absolutely obsessed with the Titanic - not the film, the actual boat. I'd draw diagrams about it and theorise that if it was built in a different way, it wouldn't have sunk.
CBS is proud to have been the home of David Letterman since 1993. He is truly one of the great talents of our time, and we hope things work out.
There's so much written about the Titanic, and it's hard to separate what's fact and what's fiction. My understanding is that the way the Titanic was designed, the emphasis was placed on surviving a head-on collision.
'The David Letterman Show' is a show of comedy.
Hey, you know what, I've gotta go on that 'Letterman' show. That show is so lame.
