But that was my very first time on a set and they said, you know, you have to stand on a mark. That little piece of tape that you stand on is called a mark. I kept correcting them and telling them that my name was Michael and not Mark. They said, 'No, no honey.' I was a little green.

I am terrible at memorizing things. Hence, ad-libbing.

My big running discovery was around Stanley Park in Vancouver. Miss it. That's a six-mile loop. Now I smile when I get four miles done. Age is a beast.

I am blood type O-positive, which I remember by staying 'optimistic positive.'

When my wife gets mad at me, I remind myself that she is much smarter than I am and so I probably deserve it, even if I don't really understand it!

I was fresh out of drama school and had no idea what I was doing. They hustled me along and Bill Cosby tolerated my rookie behavior. It was great. Once you have 'The Cosby Show' on your resume, you can keep going.

My wife, Bojana, is a doctor; we both work intense hours and have months when we barely see each other. It isnt easy, but we realize nobody said it was supposed to be!
