I'm the biggest geek of all. Adventure, fantasy, comic books - I can't get enough.

It's so great in Hollywood now. You have people past 40 sitting and talking about serious stuff, writing and making movies and TV, but there's laser pistols and superheroes and alien monsters involved. It's viable and mainstream.

I'm the kind of guy who, I need a watch that tells me what day it is. I need to know it's Friday on my watch. I need to look at it and go, 'Friday today.' Tomorrow I will not know it's Saturday until I look at my watch. My watchband broke, I was crippled. I have no concept of time, I have no concept of dates.

No one wants to see a person on TV who's super-ultra-cool. That's Superman, that's a thing of the past. Heroes are now flawed, and have terrible tempers, you know? They're real people.

The research I have been doing - studying how foodstuffs yield energy in living cells - does not lead to the kind of knowledge that can be expected to give immediate practical benefits to mankind. If I have chosen this field of study, it was because I believed in its importance in spite of its theoretical character.

We can't get to the $4 trillion in savings that we need by just cutting the 12 percent of the budget that pays for things like medical research and education funding and food inspectors and the weather service. And we can't just do it by making seniors pay more for Medicare.

I was a mimic when I was a child. I mimicked the teacher and made friends that way, actually. That was a very subversive activity, because I was a goody-goody who never got in trouble. But if I went off in the corner and mimicked the teacher, people loved it.

I suggest that those groups whose culture and values stress delayed gratification - education, hard work, success, and ambition - are those groups that succeed in America, regardless of discrimination.
