Heh....
My son is bipolar. He went off the deep end a couple of years ago and spent a month in a similar psychiatric ward full of people that were also, like Omni's brother's companions, fucking crazy.
He called me up at work one morning with the news that he was being released. I drove over there, got him all signed out, and we walked to the car and got in. When I turned the key, Humble Pie's "Thirty Days in the Hole" was just starting. We both fell out the doors laughing.
