A chicken farmer went to a local bar, sat next to a woman, and ordered a glass of champagne.
The woman perked up and said, "How about that? I just ordered a glass of champagne, too!"
"What a coincidence," he said, "This is a special day for me, I'm celebrating."
"This is a special day for me, too, and I'm also celebrating!," said the woman.
"What a coincidence," said the man. As they clinked glasses he asked, "What are you celebrating?"
"My husband and I have been trying to have a child, and today my gynecologist told me I'm pregnant!"
"What a coincidence," said the man. "I'm a chicken farmer.
For years all my hens were infertile, but today they're finally laying fertilized eggs."
"That's great!" said the woman. "How did your chickens become fertile?"
"I switched cocks," he replied.
She smiled and said, "What a coincidence!"
