I don't like eating the Oreo cookies by itself. I will put a few in a plastic bag, smash them into little pieces with the rolling pin and mix it up with vanilla ice cream. I also like it with mint ice cream when I can find it (without chocolate chips).
On a side note, I was in China last summer and discovered Chinese Oreos. They're also made by Nabisco, but instead of round cookies, they're long rectangular chocolate wafers with creme sandwiched in between. The whole thing is also covered in chocolate. It's really good and I was sad when I couldn't find any of them here in the states.
