"Women, they think they're so smart," he said with a sly smile, going on to explain that he'd eavesdropped on a phone conversation between his fiancé, Lynn, and her best friend, Amy "She said, 'Bill doesn't know it yet, but the only time I'm putting out is when I want to get pregnant."

"She'll never know I've already had a vasectomy!"
