How common is a reverse cookie on an Oreo?

It's impossible to say exactly how common a reverse cookie is on an Oreo. There's no official data from Mondelez (the company that makes Oreo) on this.

However, here's what we *do* know:

* It's a rare occurrence: Most Oreo enthusiasts agree that it's a rare sight.

* It's not a manufacturing error: It's not a result of a mistake in the production line. It's a natural anomaly that can happen when the cookie is being formed.

* It's probably not as rare as people think: Think about how many Oreos are produced every day. Even a very small percentage of Oreos with a reverse cookie would still be a substantial number.

So, while it's rare to find an Oreo with a reverse cookie, it's probably more common than you might think.

If you're really curious, you could try a little experiment: buy a few bags of Oreos and see how many have the reverse cookie!
