IT’S A?

A middle-aged couple named Joe and Ellen Waters
Had two stunningly beautiful teenage daughters
But the couple decided they should try once more
For the son that they had always been hoping for
After many months of trying, Ellen finally conceived
And then a healthy baby boy was finally received
Joe joyfully rushed into the nursery to see his son
Took one look and wondered what they’d done
He was horrified it was the ugliest kid he’d ever seen
He went and told his wife Ellen he wasn’t very keen
He said there was no way that he could be the dad
"Look at the two beautiful daughters we’ve had”
Then he gave her a very stern look and asked her
"Tell me honestly Ellen have you had an affair?"
But Ellen just smiled sweetly at her husband Joe
Then she looked at him and said, "Not this time no!"
