Listerine

Yesterday, I proved to myself that the mouthwash - Listerine is really potent. : - As I was having my shower, I saw something black wiggling around near the drain hole of the shower. I couldn't be sure what it was, but I guessed it must be a worm. So I took some Listerine, and poured it on the "worm". I saw it wiggle, wiggle, then after a few moments, the worm stopped moving. After I put on my glasses, I could see that it was a centipede, about 7 - 8 centimeters long, DEAD! So.. if it could kill a centipede, be sure never to swallow your mouthwash, and be sure, be rest assured that when you use Listerine, your mouth is really clean. It is VERY clean!
