Ahhhhh, Advertising

As I was rinsing out my mouth this morning with my mouthwash of choice "Listerine", I noticed the label and it said the following

24 Hour Protection
against Plaque and Gingivitis Germs

Which seems like a great ad if you are selling this type of product, then I noticed underneath this lovely add the following directions

Use every 12 Hours

So, not only are they pulling you in with the ad, but they want you to use twice as much as you need so that you buy more. You gotta love advertisors.
