While the bar patron savored a double martini, an attractive women sat down next to him. The bartender served her 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?" "I switched cocks."

"What a coincidence," she said, smiling.
