I don't know if anyone else has had this problem, but more often than I'm happy about, I have accidentally sprayed tiny bits of toothpaste into my eye. It is interesting how the experience of minty freshness translates from the sense of taste to that of pain. The sharply stinging feeling of minty freshness in my eye brings horrible new meaning to the toothpaste manufacturer's invitation to "experience a whole new dimension of freshness." Perhaps I should say "brings meaning to" since ... well ... it didn't really mean anything to begin with.
Experience a whole new dimension of freshness--in your eye! Ha-a haha haha! (maniacal laughter)
