A middle-aged couple had two stunningly beautiful daughters. The couple decided to try one last time for the son they'd always wanted.
After a few months of attempting to conceive, the wife became pregnant. She delivered a healthy baby boy nine months later.
The joyful lather rushed into the nursery to see his new son. He was horrified to find the ugliest child he had ever laid eyes on.
He told his wife, "Look at the two beautiful daughters I fathered. There's no way that's my son. Have you been fooling around on me?"
The wife smiled sweetly and said, "Not this time."
