ARMS ROOM. Includes AK-47s, RPG-7s, even a couple of Stingers. Of course, when your biggest threat is a bunker buster bomb or a fuel-air explosive device, small arms don't impress much, do they?
ANTHRAX LAB. Hey, they have to make the stuff somewhere. They also experiment with other bioweapons, including a new venereal disease normally only transmitted by goat copulation. Man, those terrorists are some serious biological researchers, at it day and night...
TERROR HQ. This is where al-Quaeda plans out their attacks, taking special care to look at kindergartens and old-age homes for their next targets (they're such brave warriors!). They also have radios to stay in touch with their fifth-columnists around the world, to give liberal reporters the latest figures on "civilian casualties," and to get their marching orders from Saddam Hussein.
HAREM. Most of Bin's women need to keep their veils on at ALL times!
GOAT CAVE. For those times when the harem just isn't enough.
BIN-LADEN'S HOME. Deep in the ground, like the rat he is. He watches CNN to see how the "neutral" media is spinning his story. Too bad he won't live to see his death reported there.
