We start a laugh at others by getting an infallible laugh at ourselves.

The commonplace wit arranges incidents to make someone he dislikes ridiculous; his attitude is the attitude of the superior person.

He is nearly always--often unintentionally--offensive; he repels the public sometimes in irritation, sometimes in amusement, for they often see point in his joke, but see a greater joke in him, and they are often laughing, not at his joke, but at himself.

Let us for our salvation avoid the attitude of the superior person.

Don't make sport of others--make it of yourself.
