Laughter is wine for the soul – laughter soft, or loud and deep, tinged through with seriousness. Comedy and tragedy step through life together, arm in arm, all along, out along, down along lea. A laugh is a great natural stimulator, a pushful entry into life; and once we can laugh, we can live. It is the hilarious declaration made by man that life is worth living.
