Humor is kindly. Wit is caustic.

Humor is the ability to discern in a kindly way the folly in what is considered normal, sublime behavior, and to discern the discrepancy in what appears as a truth.

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

That's part of our policy, is not to be taken seriously, because I think our opposition, whoever they may be, in all their manifest forms, don't know how to handle humor.

The source of all humor is not laughter, but sorrow.

Humor is the good natured side of a truth.
