Seven days without laughter makes one weak!

He who laughs, lasts.

He who laughs last thinks slowest.

Those who can laugh without cause have either found the true meaning of happiness or have gone stark raving mad.

Laugh at your problems; everyone else does.

Laughter is the best medicine-too bad life is terminal.

Laugh alone and the world thinks you're an idiot.

Blessed are those who can laugh at themselves for they never cease to be amused.
