Some people get it.

When people describe America it’s interesting what they compare it to. One man though made the comparison of the Untied States to a rattlesnake:

I recollected that her eye excelled in brightness, that of any other animal, and that she has no eye-lids—She may therefore be esteemed an emblem of vigilance.—She never begins an attack, nor, when once engaged, ever surrenders: She is therefore an emblem of magnanimity and true courage.—As if anxious to prevent all pretentions of quarrelling with her, the weapons with which nature has furnished her, she conceals in the roof of her mouth, so that, to those who are unacquainted with her, she appears to be a most defenceless animal; and even when those weapons are shewn and extended for her defence, they appear weak and contemptible; but their wounds however small, are decisive and fatal:—Conscious of this, she never wounds till she has generously given notice, even to her enemy, and cautioned him against the danger of treading on her.—Was I wrong, Sir, in thinking this a strong picture of the temper and conduct of America? The poison of her teeth is the necessary means of digesting her food, and at the same time is certain destruction to her enemies—This may be understood to intimate that those things which are destructive to our enemies, may be to us not only harmless, but absolutely necessary to our existence.

The author?

Benjamin Franklin.

Benjamin Franklin is famous for his sense of humor. In 1751, he wrote a satirical commentary in his Pennsylvania Gazette suggesting that as a way to thank the Brits for their policy of sending convicted felons to America, American colonists should send rattlesnakes to England. 

Some history of the Gadsden flag and also a great passage that has since been attributed to Franklin, say what you will these guys were smart and all this time later it still shows.
