That Oreo sludge sounds good and gross at the same time.  I used to occasionally fill a whiskey glass halfway with milk and submerge an Oreo there so that the entire cookie would be dipped and my fingers wouldn't get milk on them. (I used a spoon)  That was delicious, but an entire carton of milk??? Oreo Sludge??? Kind of makes me want to throw up.  Too much of a good thing does that to you.
