One such measure stands out to me - they described the accuracy of some computer hardware as “missing one blade of grass while mowing a lawn the size of a football field flying from a helicopter over mile up in the air” (paraphrasing and using quotes to demarcate the interesting bit; not a literal quote).

I guess it’s effective and memorable because even months later, I remember the gist of the accuracy claim (though not the hardware item name)

I am not American, but I love illustrations. A number + an amount of giraffes that illustrate it are better than just the number.
