An old astronomer there was
Who lived up in a tower,
Named Ptolemy Copernicus
Flammarion McGower.
He said: “I can prognosticate
With estimates correct;
And when the skies I contemplate,
I know what to expect.
When dark’ning clouds obscure my sight,
I think perhaps ’twill rain;
And when the stars are shining bright,
I know ’tis clear again.”
And then abstractedly he scanned
The heavens, hour by hour,
Old Ptolemy Copernicus
Flammarion McGower.
