Good one!

That was awesome. And unsettlingly true.
There was an interesting passage in the biography John Adams, by David McCullough, where Adams writes of teaching (home-schooling!) his son John Quincy, who was seventeen:
If you were to examine him in English and French poetry, I know not where you would find anybody his superior... He has translated Virgil's Aeneid... the whole of Sallust and Tacitus' Agricola... a great part of Horace, some of Ovid, and some of Caesar's Commentaries... besides Tully's [Cicero's] Orations...Letter from John Adams to Dr. Benjamin Waterhouse, former tutor to John Quincy Adams, pp. 324-325In Greek his progress has not been equal; yet has he studied morsels of Aristotle's Politics, in Plutarch's Lives, and Lucian's Dialogues, The Choice of Hercules in Xenophon, and lately he has gone through several books in Homer's Iliad.
In mathematics I hope he will pass muster. In the course of the last year... I have spent my evenings with him. We went with some accuracy through the geometry of the Preceptor, the eight books of Simpson's Euclid in Latin,.. We went through plane geometry... algebra, and the decimal fractions, arithmetical and geometrical proportions... I then attempted a sublime flight and endeavored to give him some idea of the differential method of calculations...[and] Sir Isaac Newton; but alas, it is thirty years since I thought of mathematics.

That’s priceless.
