A man sat at a local bar and said:
“This is a special day, l’m celebrating.”
“What a coincidence”, said the woman next to him, “I’m celebrating, too”, she said and clinked glasses with him.
“What are your celebrating?” the woman asked.
“I’m a chicken farmer, and for years all my hens were infertile,
but today they’re finally fertile.”
“What a coincidence”, the woman said, “For my husband and I have been trying to have a child.
Today, my gynaecologist told me l’m pregnant! How did your chickens become fertile?”, she asked .
“I switched cocks”, he replied. “What a coincidence”, she said.
