Required step #1 in obtaining your monthly crazy check from SSD. A well known fact in the urban jungle, is to engage in one act each six months nuts enough to get you arrested, and the police report is absolute proof you're crazy and disabled. Barking at a cat in a tree while naked. Ordering a quarter pounder and fried bats wings from McDonalds and refusing to leave the counter until Marvin Gay does a reunion tour. Barking at patrons at an expensive restarant while plucking a dead chicken and reading the New York Times.
You get the idea. A document from the state system outweighs any doctor.
