A man went into a local tavern and took a seat at the bar next to a women 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.
