I did stand-up comedy for 18 years. Ten of those years were spent learning, four years were spent refining, and four years were spent in wild success. I was seeking comic originality, and fame fell on me as a byproduct. The course was more plodding than heroic.

I knew I wanted to be in comedy but the path of least resistance was doing stand-up in folk music clubs where I could get on stage. I guess you could get up no matter how bad you were and you didn't have to audition. You just got up. Everything else required an audition and if you auditioned for a TV show, you would stand in line with a hundred other people. But at the clubs, it was okay just to get up, so that's why I started in stand-up.

I thought if I had a Twitter feed and say I had a following of a 100,000, that means 100,000 of them would be interested in my book. It was logical, but it didn't turn out to be true. It turned out if I had a Twitter feed of a 100,000, four of them were interested in my book.

I would get records by Earl Scruggs... I would tune my banjo down and I'd pick out the songs note by note. Learned how to play that way. I persevered. There was a book written by Pete Seeger, who showed you some basic strumming and some basic picking... And I kind of worked out my own style of playing.

Always do business as if the person you're doing business with is trying to screw you, because he probably is. And if he's not, you can be pleasantly surprised.

I never touched a gun in my life. That and that alone forever doomed me to middle management.

So much emotion can be brought in an animated film that's very hard to get in a live-action film. I haven't quite put my finger on why, but it might be because the characters can make facial expression that, if you made them in a movie, they'd call them corny.
