a Germ-X Percent
A number that sounds impressive but means nothing to anyone who has ever been sick.
'99.99% germ killer!' That's just 1% of germs saying, 'I'm not scared.'
I used Germ-X and still got sick. That 0.01% of germs is a menace.
99.99% is like saying you're 99% full, you're still hungry.
