I have never examined the subject of humor until now. I am surprised to find how much ground it covers. I have got its divisions and frontiers down on a piece of paper. I find it defined as a production of the brain, as the power of the brain to produce something humorous, and the capacity of percieving humor.
Mark TwainIf there is one thing that is really cheerful in the world, it is cheerfulness. I have noticed it often. And I have noticed that when a man is right down cheerful, he is seldom unhappy for the time being. Such is the nature of man.
Mark TwainYou can't reason someone out of something that they weren't reasoned into in the first place.
