An elderly couple are having an elegant dinner to celebrate their 75th wedding anniversary.
The old man leans forward and says to his wife, “Dear, there is something that I must ask you. It has always bothered me that our tenth child never quite looked like the rest of our children. Now I want to assure you that these 75 years have been wonderful, but I must know, did he have a different father?”
The wife drops her head, unable to look her husband in the eye, and says, “Yes. Yes he did.”
The old man, with a tear in his eye asks, “Who? Who was the father?”
The woman says nothing at first, then, she finally says, “You.”
