All. All of them.

The proper procedure for eating Oreos is as follows:

One: eat a single Oreo. Telling yourself you're going to be good.

Two: have one more because it's only one more

Three: realize you've eaten every single Oreo in the house. Feel guilty.

Four: go to the store and buy replacement Oreos so your family doesn't know about your shame

Five: go to sleep, and repeat as necessary the next day
