The men in the white coats have regained control
The lunatics have been running the asylum for a while, but they are being rounded up and returned to their cells. Looks like the doctors have regained control of the Senate, meaning both wings of the hospital will no longer be run by the feeble-minded. There are a few other loose nuts being taken care of now...(Damn! I forget where I saw this picture.)
Update 9 November: I think I borrowed it from a 6 May 2006 post at The Whiskey Bar (Billmon)--the photo was up there again yesterday.
