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. Im celebrating.

Im celebrating, too, she said, clinking glasses with him.

What are you celebrating? he asked.

For years Ive been trying to have a child, she replied, Today my gynecologist told me Im pregnant!

Congratulations, the man said, lifting his glass. As it happens, Im a chicken farmer, and for years all my hens were infertile. But today theyre finally fertile.

How did it happen?

I switched cocks.

Ill drink to that, she said, smiling.
