Haha, true, although you could say that words always have a potential to smear - like a jam doughnuts do have the potential to smear and therefore according to some security screeners it should be in a one litre bag within a bottle 100ml or less.

On a serious note, I do sometimes wonder if they'd ban words, along with eyebrow tweezers, liquor-filled chocolates, pralines, truffles, jam doughnuts, pens, make-up on one's face etc etc... Oh that's right, many words have been banned already. Never mind.
