Does the cheese come out of cow with holes already in it?

Here's why:

* Cheese is made from milk: Cows produce milk, not cheese.

* Holes are created during the cheesemaking process: The holes in Swiss cheese, for example, are caused by bacteria that produce carbon dioxide gas as they ferment the milk.

So, the next time you see a delicious block of Swiss cheese, remember those holes are a result of clever cheesemaking techniques, not a natural cow product!
