Farmer and lady in a bar - celebrating

 A chicken farmer goes into a bar, takes a seat next to a woman, and orders a glass of champagne. The woman perks up and says, "How about that? I just ordered a glass of champagne, too!"

He turns to her and says, "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 clink glasses and he asks, "What are you celebrating?"

"My husband and I have been trying to have a child. 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 cocks," he replies.

"What a coincidence," she said.
