A man lies on his deathbed surrounded by his family: a weeping wife and four children. Three of the children are tall, good-looking, and athletic; but the fourth and the youngest is an ugly runt.

"Darling wife," The husband whispers, "assure me that the youngest child really is mine. I want to know the truth before I die, I will forgive you if..."

The wife gently interrupts him. "Yes, my dearest, absolutely, no question, I swear on my mother's grave that you are his father."

The man dies, happy.

The wife mutters under her breath: "Thank God he didn't ask me about the other three!"
