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

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.

Humor is the good natured side of a truth.

If I had no sense of humor, I would long ago have committed suicide.

Pure and complete sorrow is as impossible as pure and complete joy.
