Life was a fairy-tale, then, it is a tragedy now. When I was 43 and John Hay 41 he said life was a tragedy after 40, and I disputed it. Three years ago he asked me to testify again: I counted my graves, and there was nothing for me to say. I am old; I recognize it but I don't realize it. I wonder if a person ever really ceases to feel young - I mean, for a whole day at a time.

Explaining humor is a lot like dissecting a frog, you learn a lot in the process, but in the end you kill it.

I have criticized absent people so often, and then discovered, to my humiliation, that I was talking with their relatives, that I have grown superstitious about that sort of thing and dropped it.

Right is right, and wrong is wrong, and a body ain’t got no business doing wrong when he ain’t ignorant and knows better.

They say that you can't live by bread alone, but I can live on compliments.

An average English word is four letters and a half. By hard, honest labor I've dug all the large words out of my vocabulary and shaved it down till the average is three and a half... I never write metropolis for seven cents, because I can get the same money for city. I never write policeman, because I can get the same price for cop.... I never write valetudinarian at all, for not even hunger and wretchedness can humble me to the point where I will do a word like that for seven cents; I wouldn't do it for fifteen.

... No photograph ever was good, yet, of anybody - hunger and thirst and utter wretchedness overtake the outlaw who invented it! It transforms into desperadoes the weakest of men; depicts sinless innocence upon the pictured faces of ruffians; gives the wise man the stupid leer of a fool, and the fool an expression of more than earthly wisdom.
