Johnny Galecki quotes:

It's that one thing that you're passionate about, that you end up developing tunnel vision for and everything else tends to fall by the wayside. Passion is appealing and universal.

I used to know Jennifer Love Hewitt. We lived in the same apartment building when I was about... jeez, I guess it was when I was doing 'Christmas Vacation', so I was about 13 or 14.

You get to a certain point - gratefully - when you're out of your twenties, and you realize how fleeting life is. So, it becomes important to feel as if the people in your life know exactly how you feel about them at all times.

We've all seen great actors and actresses who are missing a certain chemistry. And it's not about getting along or not getting along.

Scientists are not these guys in lab coats deep in the inner bowels of universities and hospitals with their Bunsen burners. They're the people molding the culture that we live in, the future of our culture, and the technology we rely on every day.

You get to a certain point - gratefully - when youre out of your twenties, and you realize how fleeting life is. So, it becomes important to feel as if the people in your life know exactly how you feel about them at all times.

Entourage' is a great show, but it's fantasy. I spent my twenties in L.A. in this business, and my life didn't look anything like that. 'Big Bang' reflects a side of men that is rarely shown. We see their flaws - all of them.

I was a huge theater geek growing up, and that was not the easiest thing in the world, especially growing up in Chicago, where sports are really the norm. I was always off to the theater at night, from 7 years old on. Friends there in the Midwest who could talk to you about the idiosyncrasies of 'Pippin' were few and far between.

You know, I read the papers and I watch the news a lot. I watch 'Dateline' and '48 Hours'. And I think we have a tendency to become terrified of one another, thinking that there is a serial killer that is on either side of you.

Right now, Im very healthy. I have no vices left. Except sugary breakfast cereal. And absinthe, of course.

People are complicated; you put two of them together and it's generally a mess, but hopefully a beautiful mess.

Perhaps 'Big Bang' fans feel so protective of the show because it is, despite being a hit show on a big network, something of a word-of-mouth phenomenon.

Right now, I'm very healthy. I have no vices left. Except sugary breakfast cereal. And absinthe, of course.

When I'm back home in Chicago, since 'Roseanne' was such a Midwestern, blue-collar show, that's what sticks out in people's minds.

I bought a little hideaway up north, so I'll ship my motorcycle up there. It's much less dangerous than West Hollywood.

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.

There is that stereotype of a nerd with the high pants and pocket protector and that kind of thing. That can sustain comedy for maybe a movie - hence the 'Revenge of the Nerds' franchise - but not for hopefully years on the air. It's a sight gag, not a story.

Comedy is similar to hockey... in only one way. You get a lot of credit for assists. So I try to serve whatever the intention is, be it the joke or the story or the scene or the moment or the kiss, even if it's not my joke or moment.

I don't know what to do with myself between films. I end up doing unhealthy things like shopping or drinking. I'm pretty schizophrenic about it.

Just selfishly, I wanted to be associated with something as synonymous with cool and cutting edge and artistic as CBGB. People are aware of that, at least, even if nothing else. That's something to be proud of, to be a small part of the association with something like that.

It took me a long time to realize that to walk around without a certain amount of belief in myself, to walk onto a job with my tail between my legs, wasn't behooving anyone else.

I'm not at all competitive. I'd rather play Solitaire than ping-pong.

It's always a really great thing to have an actor that does make you want to up your game. It naturally motivates you to do and try things that maybe you wouldn't necessarily do or try.

We didn't have a TV because we didn't have a whole lot of money. My parents would have their friends over - their friends who thought, 'How can you live without a TV?'

I know a lot of incredibly, profoundly talented, skilled people that aren't given certain opportunities or any opportunities, and that aren't working.

In a series, you really need to stay open-minded. It's not like a play or a film, where you can create and fully commit to your character's back-story.

I love to work. I absolutely love to work.

We didn't have a TV because we didn't have a whole lot of money. My parents would have their friends over - their friends who thought, 'How can you live without a TV?

It's never been a priority for me to concentrate on the likability of the character.

I haven't really addressed those rumors because why defend yourself against something that isn't offensive?
