Elaine and Oreos?

Tonight (12/9) we had another old episode. I have a small B/W TV so I need confirmation on this: Was Elaine eating Oreos? From what I could make out, she was licking out the centers. If I remember correctly, she's done this on other episodes. I want to say it was the Keith Hernandez one, but I'm not absoulutely positive.

Can anyone give more documention to this Oreo fetish?

Yes, she was eating Oreos from the middle out (after first unscrewing them, of course). George prefers to munch without disassembling. Elaine does have a history of using this technique. The Keith Hernandez episode may have been it, but I'm not sure, either.
