Farmer and the Pregnant Lady

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'm celebrating."
"This is a special day for me too, I'm also celebrating!" says the woman.
"What a coincidence" says the man. As they clinked glasses the farmer asked, "What are you celebrating?" "My husband and I have been trying to have a child, and today my gynaecologist told me that I'm pregnant!"
"What a coincidence," says the man ... "I'm a chicken farmer and for years all my hens were infertile, but today they're finally laying fertilised 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"
