This bottle of hand sanitizer reads "Kills 99.9% of most common germs that may make you sick".

Wait a second. Kills 99.9% of most of them? What's most? 51%? So this hand sanitizer might actually be only killing half of these germs?

I'm going to see if I can get away with that tricky wording at work. "Hey boss, I finished 99.9% of most of what you told me to do."
