Johnny Galecki

It's always interesting for me to watch the pilot of an established show because you see how the writers and actors weren't really sure what the show was and what the dynamics were. If you look at the pilot for 'Seinfeld,' for example, it's practically unrecognizable.

Growing up in Chicago, I was a theater nerd. That might be very cool on the East Coast, but in Chicago, it's really the athletes that come in No. 1 on the cool scale. Maybe musicians after that. Community theater? That's way down the list, my friend.

As they say, there are two rules in improv: Never say no, and never ask why. When another actor asks 'Why?' or says no to something you're suggesting, then it's very clear that they're putting the onus on you, because they're not comfortable with it themselves.

I've found that in now having experienced what it's like to make records and just through growing up in general that you should be expressive about what's affecting you instead of trying to sing about a subject just for the sake of other people getting something from it.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
