chips and chrisps

I dunno if watching Armageddon again this weekend brought this on, but earlier today I was eating a bag of O'Boises 'Potato Crisps' when it began to bother me that they were called 'Crisps' and not chips. I debated with nate. At first we considered that the thing that defines a chip is the presence of potatos. But that isn't right- because O'boises aren't chips, yet are obviously made with at least some potato. Plus there are Corn Chips which have no potato in them, but yet still are labeled as 'Chips'. We concluded that chips come in bags and crackers in boxes, but that still doesn't explain these o'boises yet. I worried about this so much, that it became extremely apparant that I'm really working too hard to avoid finishing my paper on propaganda & art that is due before thanksgiving. ugh.
