Well I'm pretty lame and just eat Oreos just like normal. My wife, however, crumbles them up and puts it in her ice cream. And my daughter, that little girl is bonkers; she will gut the Oreo and eat the middle and just throws the cookies away! WTF!
See, for me, neither one of the components of Oreo is great on its own. It's when they are together that the Oreo is most enjoyable.
