"Life is too hard to maintain a constantly serious outlook. You have to laugh at yourself and the world now and then-see humor in undesirable circumstances, even harsh situations-or you will either rot from the inside or go stark-raving mad. Humor is power against the worst oppression. It lightens heavy burdens; it allows one to smile while in agony; it eases excruciating pains. In short, humor makes the intolerable tolerable."
