Everything human is pathetic. The secret source of humor itself is not joy but sorrow. There is no humor in heaven.

Humor is the good natured side of a truth.

The political and commercial morals of the United States are not merely food for laughter, they are an entire banquet.

Humor is mankind's greatest blessing.

Train your eyes and ears; train your nose and tongue. The senses are good friends when they are trained. Train your body in deeds, train your tongue in words, train your mind in thoughts. This training will take you beyond sorrow.

Parting is such sweet sorrow that I shall say goodnight till it be morrow.
