Gary was chuckling at the bar when his friend Steve joined him. "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 fiancee and her best friend.

"She said, 'Gary doesn't know it yet, but the only time I'm putting out is when I want to get pregnant."

At this, Gary doubled over with laughter, and Steve looked at his friend with some consternation,

"I'd be mad as a hatter! Why aren't you?" he asked.

"Why get mad?" answered Gary. "She'll never know I've had a vasectomy!"
