Oreo Rules

A Simple, Village Undertaker confesses to straying (I'll refrain from calling it a grave sin) and his story indirectly raises the macro-question of proper Oreo etiquette. Which is correct?

1. You gently separate the cookie, then eat each side.
2. You gently separate the cookie, then lick off the filling before eating the chocolate wafers.
3. You dunk the cookie in milk and then eat the entire cookie.
4. You pop the entire cookie into your mouth, then take a sip of milk before chewing it up.
5. You use any of these techniques but only eat three at a setting.
6. There are no limits to any technique or amount, you Communist.
7. Hey, what happened to all of the Oreos?

[By the way, for a limited time you can get watermelon-flavored Oreos.]
