The man sitting at the the bar was enjoying his double martini, when an attractive women sat down next to him. She ordered a glass of orange juice, and the man turned to her and said, "This is a special day. I'm celebrating."
"I'm celebrating, too," she replied, clinking glasses with him.
"What are you celebrating?" he asked.
"For years I've been trying to have a child," she answered, "Today my gynecologist told me I'm pregnant!"
"Congratulations," the man said, lifting his glass. "As it happens, I'm a chicken farmer, and for years all my hens were infertile. But today they're finally fertile."
"How did it happen?" she asked.
"I switched cocks," he answered.
Smiling broadly she said, "Gee, what a coincidence."
