I am laughing after I looked at the frequency chart because this was part if some fictional nonsense that I read many years ago.
Decades ago.
I didn’t put the joke together until today when I looked at the chart, which is funny because I’ve done a little bit of cryptography when I was young and I could name the common letters off the top of my head.
But until this day I did not put that joke together. In the back of my mind, it is from a book called Bored of the Rings by the Harvard Lampoon.
I don’t know if I still have that book but if I do I will now be compelled to go find it and see if my memory is correct.
