I used to think that everyone was just being funny. But now I don’t know. I mean, how can you tell?

I said of laughter, “It is mad,” and of pleasure, “What use is it?”

He who laugheth too much, hath the nature of a fool; he that laugheth not at all, hath the nature of an old cat.

There is nothing sillier than a silly laugh.

Laughter always arises from a gaiety of disposition, absolutely incompatible with contempt and indignation.
