The Japan-US Friendship Commission - i.e. The "We realize that your nation may some day eclipse ours in economic strength so please don't be mad at us for those Atomic bombs we dropped on you and be our friends forever and ever" Commission. Oh, and in case you were wondering, we don't appear to have any "Friendship Commissions" with any other countries.
National Reconnaissance Office - When you think about it, such an agency seems obvious and inevitable. Still, that scary silver medallion gives me the creeps.
United States Mission to the United Nations - "...the United States delegation to the United Nations, along with a staff of more than 100 persons, carries out our nation's participation in the world body." Does it really require a staff of 100 to assist Bush flipping off the UN every six months or so?
Western Hemisphere Institute for Security Cooperation - Formerly the "School of the Americas" and the training school for numerous South American dictators. It's been a sore point for the U.S. government for a while now, which is why they changed the name. Here is a group that has been a dedicated watchdog of the SOA/WHINSEC since 1990.
Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICMNEW) - Fine. Do you think they could take care of all the crap in my yard?
