I do actually use a boxing trainer when I train for stand-up.

Comedians work great as actors because they're good under pressure. With a lot of actors, you have to make them feel like everything's going really well to get a good performance out of them. But, if you have a comedian on the set, you can tell them, 'Hey, you really are screwing this up,' and then they just get better.

I always tell my kids to cut a sandwich in half right when you get it, and the first thought you should have is somebody else. You only ever need half a burger.

There’s a need to perfect things in a writers’ room, and that can take a lot of fun out of a show sometimes. It’s a struggle. It depends on your personality. Some people love working with a writing staff. I had a great writing staff on Lucky Louie, but it sometimes felt like Congress or something.

Don't text or twitter during the show. Just live your life. Don't keep telling people what you're doing. Just, because also - also - it lights up your big dumb face.

Rob McElhenney who runs 'It's Always Sunny in Philadelphia.' That show absolutely kills me and I am stunned by the consistency of greatness it has maintained over what is now a record breaking amount of seasons ... How do you do that for so many years? My 14-year-old daughter and I watch it together and we both laugh crazy hard.

I've had, what, two years? Probably five good years. Before that I had twenty years of uncertainty and suffering and ego destruction and poverty. All those things. That'll always outweigh the good times.
