Have you ever stopped to wonder whether Cottonelle brand toilet paper has any cotton in it? Well, of course it does–”cotton” is right there in the name, right? That’s what Ed had always thought. Then he saw a sign on the shelf at Sam’s Club that challenged his assumptions. Not that he had really given toilet paper ingredients enough thought to form any assumptions. That’s the thing with toilet paper: unless you have an allergy or are particularly eco-conscious, you don’t really think about what’s in it at all. “I guess I always assumed with the name of the product, it already had [cotton] in it…” Ed wrote when he sent us this picture.
