I don't stop eating when I'm full. The meal isn't over when I'm full. It's over when I hate myself.

Everything that people say is testable.

My last name is Szekely. Sounds like Saykay. When I was a little kid I had an instructor in camp who called me Shnizneckely. He would make fun of my name and it hurt my feelings because I was a little pussy and I cried. He said, 'Well, how do you say it?' I said, Seekay. So he wrote 'C.K' on my jersey and everything. He made my name 'C.K' and I just stuck with it.

People are always fighting for attention with things now because there's so much content. Actually, if you don't tell people stuff - you just keep your mouth shut - you don't have to whisper it, you just don't yell. Take the bullhorn off your mouth and it's a secret.

Performing comedy, you develop a rhythm of ideas and laughs. I live for it.

Credibility lasts about two cycles of bad material, and then you'll probably never get it back. If you let people down, that's really hard to come back from - harder than climbing from nothing to something, even.

When you're young as a comic, you don't have a lot of leverage.
