Have you just begun to notice that?

Prof. Wutheridge:
Same trouble with my book. Can't find the words. Dudley:
[holding up an old Roman coin]
Even when you had this coin to inspire you? Julia Brougham:
Why, that's the one that you gave to Henry, professor. Dudley:
Yes, I, uh, I stole it off the table. Prof. Wutheridge:
You wasted your time, Dudley. It's worthless. Dudley:
Oh, on the contrary. This is one of the rarest of all antiquities. Only 100 of these coins were minted by Julius Caesar 2000 years ago. That was when Cleopatra visited Rome. Presumably, these coins were used to pay her hotel bill. Prof. Wutheridge:
I never knew that. Dudley:
Well, nobody knew about it, except, uh, Caesar's wife. Julia Brougham:
She was suspicious? Dudley:
Definitely. She did *not* share her husband's admiration for Cleopatra. So she had these coins destroyed, melted into ornaments for herself. This is the one she missed. It's an unwritten chapter in history, and you, professor, will write it. Prof. Wutheridge:
[showing some growing curiosity]
Do you know any more stories like that? Dudley:
Oh, any number of them. Prof. Wutheridge:
You're a curious fellow, Dudley. Julia Brougham:
Have you just begun to notice that?
