Listerine and advertising's other lying liars

If you thought Enzyte’s promise to make your penis bigger was club-footed false advertising, wait until you see Mental Floss’s list of shameless false-advertising schemes. The biggest offender is Listerine, which claimed its product treated basically every ailment under the sun in 1921, and was still saying it was better than dental floss in 2005. (It also invented halitosis so it could then cure it, but that isn’t mentioned.) Really, the whole list could have been about Listerine.
