Daily Joke: The odd one out

An elderly couple is 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.”
