A man sat at a local bar and said:
“This is a special day, I’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 I’m pregnant!
How did your chickens become fertile?”, she asked.
“I switched cocks”, he replied.
“What a coincidence”, she said.
