Jack and his wife lived in Arizona where the summers are very hot. One day they awoke to a particularly severe heat wave. As he stepped out of the shower he complained to his wife saying, “it’s just too hot to wear any clothes on a day like this. What would the neighbors think if I mowed the lawn with no clothes.”
A man went into a local bar and took a seat next to a pretty woman. 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 for years. Today, my gynecologist told me I’m finally pregnant!" And she clinked glasses with the farmer again.
"By the way" she asked, "How did your chickens become fertile?" "I switched cocks," the farmer replied.
To which the woman smiled and said, "What a coincidence."
