I was horrible at science and math. I couldn't pass a test to save my life! I'm surprised that it didn't take me until I was 20 to graduate. That's why my role is so cool - Grissom is the complete opposite of me.

I know a lot of actors who've just gotten bitter because they did something and then nobody ever saw it or whatever.

Now I'm seen by more people in one episode than I was in 20 years of theatre and movies. It's gratifying to have an impact on 25 million people a night, but I can say goodbye to my lunch-pail life as a working actor. I'm scared I might be a celebrity.

If I could change on thing about myself, I would: Have better knees. Mine are shot because of injuries. You're only as good as your legs, whether you're an athlete or an actor.

I can't figure out how they decide on those things. So I don't have any regrets about anything that I did that didn't get a lot of people to see it.

I won't miss Grissom. It was a complete life for me that's reached its end, and it's reached it in the right way, I think. So I won't miss Grissom. And I hope that the audience won't miss him either.

Corporate Hollywood thinks I'm a geek to go back and do theater. They don't understand why I don't want to be a movie star, why I'm not pursuing Mel Gibson's roles.
