A chicken farmer went into a local tavern and took a seat at the bar next to a woman patron and ordered a glass of champagne.

The woman perks up and says, "How about that? I just ordered a glass of champagne, too!"

He turned to her and said, "What a coincidence. This is a special day for me; I'm celebrating."

"This is a special day for me, too, and I'm also celebrating!," says the woman.

"What a coincidence," says the man. They clinked their glasses and he asked, "What are you celebrating?"

"My husband and I have been trying to have a child," she replied. "Today, my gynecologist told me I'm pregnant!"

"What a coincidence," says the man. "I'm a chicken farmer. For years all my hens were infertile, but today they're finally fertile."

"That's great!" says the woman, "how did your chickens become fertile?"

"I switched *****," he replied.

"What a coincidence," she said.
