Doesn't have to be a serious one.
I always liked that poem you posted. But the first time that I ever heard it was on an episode of The Little Rascals that I was watching where Alfalfa was reciting it. I happened upon it again a few years later when we read it during an English Literature class in school.
A Noiseless Patient Spider
by Walt Witman
A noiseless patient spider,
I mark’d where on a little promontory it stood isolated,
Mark’d how to explore the vacant vast surrounding,
It launch’d forth filament, filament, filament, out of itself,
Ever unreeling them, ever tirelessly speeding them.
And you O my soul where you stand,
Surrounded, detached, in measureless oceans of space,
Ceaselessly musing, venturing, throwing, seeking the spheres to connect them,
Till the bridge you will need be form’d, till the ductile anchor hold,
Till the gossamer thread you fling catch somewhere, O my soul.
Amirite lost its culture years ago.
IN dreams I see the Dromedary still,
As once in a gay park I saw him stand:
A thousand eyes in vulgar wonder scanned
His humps and hairy neck, and gazed their fill
At his lank shanks and mocked with laughter shrill.
He never moved: and if his Eastern land
Flashed on his eye with stretches of hot sand,
It wrung no mute appeal from his proud will.
He blinked upon the rabble lazily;
And still some trace of majesty forlorn
And a coarse grace remained: his head was high,
Though his gaunt flanks with a great mange were worn:
There was not any yearning in his eye,
But on his lips and nostril infinite scorn.
"Ozymandias" — Percy Byssche Shelley
