This subtle speech was aimed to please
The crow, and it succeeded:
He thought no bird in all the trees
Could sing as well as he did.
In flattery completely doused,
He gave the “Jewel Song” from Faust.

But gravitation’s law, of course,
As Isaac Newton showed it,
Exerted on the cheese its force,
And elsewhere soon bestowed it.
In fact, there is no need to tell
What happened when to earth it fell.
