Two elderly gentlemen were visiting. "I guess you're never too old," the
first one boasted. "Why just yesterday a pretty college girl said she'd be
interested in dating me. But to be perfectly honest, I don't quite
understand it."
"Well," said his friend, "you have to remember that nowadays women are more aggressive. They don't mind being the one to ask."
"No, I don't think it's that."
"Well, maybe you remind her of her father."
"No, it's not that either. It's just that she also mentioned something
about carbon 14."
