Well as you can see on the WoW we get tin foil hats to all those engs out there...all 2 of you.
Found this post it was rather well done. Basicly its the secret cow level.

Also if you look at the screenshots on the tinfoil hat page and look at their names you might notice some of them coming from a recent movie. Also if you mouse of the pictures you will see a quote from the movie as well. "Give the Armory nothing, but take from it everything!"
