Spaw: re "carnal knowledge", the first scene of Tom Stoppard's play Arcadia opens with the exchange:
Thomasina: Septimus, what is carnal embrace?
Septimus: Carnal embrace is the practice of throwing one's arms around a side of beef.
a few pages later, it goes on to:
Thomasina: If you do not teach me the true meaning of things, who will?
Septimus: Ah. Yes, I am ashamed. Carnal embrace is sexual congress, which is the insertion of the male genital organ into the female genital organ for purposes of procreation and pleasure. Fermat's last theorem, by contrast, asserts that when x, y, and z are whole numbers each raised to power of n, the sum of the first tow can never equal the third when n is greater than 2.
(Pause)
Thomasina: Eurghhhh!
Septimus: Nevertheless, that is the theorem.
