A couple is taking a tour through the Natural History Museum.
They ask the tour guide:
“How old is this dinosaur skeleton?”
He replies:
“It is sixty-five million and fourteen years and three months old.”
“Wow! Amazingly, you can tell this precisely. How do you do that? Is it with carbon dating?”
“I don’t know,” says the guide.
“But when I first came here they told me it was sixty-five million years old. And I started here fourteen years and three months ago.”
