I played a nerdy guy on 'CSI: NY' for nine years. I want to be bad for a while. I want to be really, really bad.

I'm pretty lucky to work on both 'CSI: NY' and 'Supernatural.' Not bad gigs!

On 'CSI: NY,' the audience knew I was a really good guy, and I caught the bad guy.

I was never really good in school.

I was really good at being a bad guy.

I don't want to do the nerdy, goofy guy again. That was really fitting for the 'Napoleon' world, but that's kind of where I want it to stay.
