Dating
Two elderly gentlemen were talking.
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."
