A chicken farmer went into a local tavern and took a seat at the bar next to a woman patron and orders 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 glasses and he asked, 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 replied. What a coincidence, she said.
