If Thomas Jefferson had heard us, he probably would have said, 'We shouldn't have free speech.'

The type of athletes we draft still need types of versatility on the defense side of the ball, run the offense. You should still be concerned on the offense side of the ball.

Credit is like a looking glass which when once sullied by a breath may be wiped clear again but if once cracked can never be repaired.

I feel like the Internet has embraced the pizza dance. I feel appreciated for once in my life.

When I work with artists, I give them a general guideline of what my vision is. Then they're going to speak their minds on how they view it, too. The song that defines 'Neon Future' the best is the title track. I wrote that with Luke Steele of Empire of the Sun. It's through his words. We had an amazing songwriting session together, connecting.

Twins are a high-risk pregnancy, by definition. The quieter I am, the longer I can keep them growing.

We must fight intolerance, racism and the far-Right.

But those who believe that what our people desire is big government are living in a state of delusion.

I think there is this whole part of America that people overlook. I think they know it's there, but they tend to overlook it, become ignorant to it, and refuse to see it for what it is.

I've always been interested in UFOs.

In America the biggest is the best.

Some eco groups suggest that as many as 73 million sharks are killed globally every year. Hammerheads, blue sharks, mako sharks - they're disappearing, and they ain't coming back.

Once you get everything out of your head about what everybody else is going to think, will radio play it - and I hope they do, I really do - once you shed all of that and just be who you are, that's who I am. That's taken a lot of growing up. I've come into myself musically and as a woman, and I hope to keep growing. If you don't grow, you die.

The best evidence that time travel is impossible is the fact that we haven't been invaded by hordes of tourists from the future.

What is a rebel? A man who says no.

Although a man may wear fine clothing, if he lives peacefully; and is good, self-possessed, has faith and is pure; and if he does not hurt any living being, he is a holy man.

The strands of the DNA double helix are held together by hydrogen bonding interactions between the complementary base pairs. Heating DNA in solution easily breaks these hydrogen bonds, allowing the two strands to separate - a process called denaturation or melting.

I never really thought of myself as a musician. I'm not saying Sonic Youth was a conceptual-art project for me, but in a way, it was an extension of Warhol. Instead of making criticism about popular culture, as a lot of artists do, I worked within it to do something.

My best actress of all time is Kate Winslet. I want to be just like her. 'Eternal Sunshine of the Spotless Mind' is one of my favourite films.

I could do a franchise for the end of everything. 'The End of Dogs,' 'The End of Cats.'

I see my daft surname as a positive thing. It first dawned on me that I had a comical name when someone called me 'Fishface' on my first day at school. I've heard all the fish jokes since then, many times over.

When I learned how millions of children go to bed hungry, my only response was, 'What can I do to help?'

Matt Bomer and I went to Carnegie Mellon for drama together.

Craft comes into acting later rather than sooner. I was somebody who had to learn through a process - a natural actor doesn't need to.
