There is no scientific reason to think that we even with space travel are going to survive as a species for ever certainly not by biting off the hand that feeds us which is exactly what we are doing.

I've got a real sense of three-dimensional geometry. I can look at a flat piece of fabric and know that if I put a slit in it and make some fabric travel around a square then when you lift it up it will drape in a certain way and I can feel how that will happen.

I am blessed for what I have but I believed in it from the beginning. Today the dream is the same: I still want to travel I still want to entertain and I most certainly still want to have fun.

Certain travellers give the impression that they keep moving because only then do they feel fully alive.

The intellectual is different from the ordinary man but only in certain sections of his personality and even then not all the time.

You know people talk about this being an uncertain time. You know all time is uncertain. I mean it was uncertain back in - in 2007 we just didn't know it was uncertain. It was - uncertain on September 10th 2001. It was uncertain on October 18th 1987 you just didn't know it.

We always live in an uncertain world. What is certain is that the United States will go forward over time.

Anything I've ever said I certainly was feeling at the time.

I feel like I still am struggling in a lot of different ways. I still have to fight for certain things. Certain jobs. At least I'm working and I'm thankful for that.

I get along very well with the cast of '30 Rock.' I guess I bring a certain quirkiness to the show as well. I'm just thankful they keep asking me. I didn't think I was going to be asked back so every time they say 'We want you back ' I'm screaming. I'm jumping up and down and screaming.
