Which is why it's good to have multilingual cans - if you speak Spanish, you'll notice that the listing gives the main ingredient as "polvo presionado de patata", which is much more accurate than the English side.
Also, one overlooked advantage of Pringles is that, if you take a can's worth of chips and put them into a bowl of water overnight, they'll return to a somewhat mashed potato-like consistency, which can then be used to make something more useful, such as an ashtray or paperweight.
