I just saw a commercial for a toothbrush with a built-in tongue cleaner for cleaning "the back of your tongue" cause that's where 90% of bad breath originates. I know, that's what I get for watching Seinfeld reruns.But isn't that how you make yourself throw up? Not by watching Seinfeld reruns, by touching the back of your tongue with something. This particular gesture is not going to be added to my repertoire anytime soon, 90% bad breath or not. I would rather have someone say, "You have bad breath" than "You just vomited on me."
