What a coincidence...

A man went into a local tavern and took a seat at the bar next to a female
patron.
He turned to her and said, "This is a special day, I'm celebrating."
"What a coincidence," said the woman, "I'm celebrating, too".
She clinked glasses with him and asked, "What are you celebrating?"
"I'm a chicken farmer," he replied. "For years all my hens were infertile,
but today they're finally fertile."
"What a coincidence, the woman said. "My husband and I have been trying to
have a child. Today, my gynecologist told me I'm pregnant!
How did your chickens become fertile?" she asked.
"I switched cocks," he replied.
"What a coincidence," she said.
