A chicken farmer went to a local bar... sat next to a woman and ordered a
glass of champagne.
The woman perks up and says "How about that? I just ordered a glass of
champagne, too!"
"What a coincidence" the farmer says "This is a special day for me . I am
celebrating"
"This is a special day for me too, I am also celebrating!" says the woman.
"What a coincidence!" says the farmer. As they clinked glasses the man
asked

"What are you celebrating?"
"My husband and I have been trying to have a child and today my
gynecologist
told me that I am pregnant!"
"What a coincidence "says the man."I'm a chicken farmer and for years, all
of my hens were infertile but today they are all laying fertlised eggs "
"That's great!" says the woman, "How did your chickens become fertile?"
"I used a different cock," he replied.
The woman smiled and said, "What a coincidence!".
