Let us consider that we are all partially insane. It will explain us to each other; it will unriddle many riddles; it will make clear and simple many… - Mark Twain

He had had much experience of physicians, and said 'the only way to keep your health is to eat what you don't want, drink what you don't like, and do what you'd druther not'.

You may say a cat uses good grammar. Well, a cat does -- but you let a cat get excited once; you let a cat get to pulling fur with another cat on a shed, nights, and you'll hear grammar that will give you the lockjaw. Ignorant people think it's the noise which fighting cats make that is so aggravating, but it ain't so; it's the sickening grammar they use.

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.
