My brain is like a hard drive. Once you start adding new information, you start cutting off old information.

I like to say there's certain things you can't take back: One of them is 'I love you,' and one of them is bullets.

You know, Castle, like anyone else, is a human being first. If you take a human being - especially a vain one like 'Castle' -and you bring in a gorgeous woman and have sparks fly, who can help themselves? What are you gonna do? Sparks happen!

I had a Ford F-250. It was a big ol' farm truck, but it wasn't a rig. That's about the biggest I've ever driven. That's what I drove back and forth to high school. I was a poor guy, and it was a truck that my uncle owned and let me drive because I had no money.

There are people who have energy that say 'don't come near me, don't get too close.' There's people like Adrienne Shelley who have the energy of 'come over here and give me a hug and if you're around me you're going to be happy about it.'

I'm comfortable only when there's a mutual attraction. That's what anyone wants. If I find out she's not attracted to me, it brings down my level of attraction to her. If I'm interested and find out she's not, I tend to cool off.
