Brudder Jon are you up to your old math tricks?
At first I thought it was tied in to a character pattern between the lines of rhyme (+2-1+2) but then I remembered something from my misspent youth, it was that Ptolemy's pi = 3.1416.
Count the numbers of characters in each word of this rhyme & it'll give you the value of pi to some power.
My guess is to the 20th power or so...
Now, back to my Cuba Libre.
