Listerine TV Commercial, 'What's It Like to Not Feel 100% Fresh? We Don't Know.'

Listerine doesn't know what it's like to not feel 100 percent fresh. While conducting a study on Listerine users called "The Study of Bold," it was found that users are more likely to stand up to a bully, hold a yoga handstand and be in a magic act. Listerine informs viewers that it kills 99 percent of bad breath germs to help you feel 100 percent in life.
