From Imladris, all the way to Rivendell
There is a story wise Elves tell.
About a plant in Der Schwarzwald
In English, "Black Forest" it is called.
Where the pinnacle of Elvish skill
Was applied...engine wear to kill.
The best and brightest gathered round
To see if a perfect formula could be found
That would almost completely banish wear
And hurting engines would repair
And so these minds so sharp and keen
Boldly went were no Elves had been
And brewed an oil bright and clean
That also glistened florescent green.
And then we humans entered the story
As Dr T spotted The Green in all its glory
And Patman, too, embraced the Green...
With the story unfolding as you have seen.
I really think we shall not see
An oil with such a history
Any time soon upon on our shelves
Unless, of course, we ask the Elves.
