Rambo - the Joe Kool fusebox is nothing special. It's just something the creators put in as a tiny "easter egg" referencing a nickname or something. You can find stuff like that everywhere in MW2 (real estate signs with the developers names, etc), and I don't doubt that they are everywhere in Black Ops too. Game designers love doing stuff like that. There are more of those fuse boxes too, in multiplayer maps. My brother was playing on Zoo and I noticed that there was a box that looked like the one from Kino, that's how I found the Joe Kool thing. I don't think its an anagram, necessarily, there isn't much that can be done with the letters G - O - K - R - D - I. I think it would be more likely to be some kind of decoder to make sense of other messages, like Brimstone to Damnation, or the three girl names... Either that or we're all completely over thinking this and there is nothing else hidden in this map. But where's the fun in that?
