Reckon you know what you're talking about?
Line up the words.
Do they? Make sense, that is,
Or did both of us miss something back there
When the question was forming,
The words were unguessed at,
And the line was a piece of string,
And no-one can say how long that is,
That is, a piece of string.
But someone always knows,
Or is certain they do,
Till they come to a knot.
What then? Ignore, untie,
Slice with a handy Alexandrian sword,
Or just assert there's no such thing
As a piece of string without knots in it,
So what's all the fuss anyway?
And besides, you know what you're talking about,
After all.
