Brickbat: Criminally Insane
A patient walked away without permission from the Graylands Mental Hospital in Australia, so staff alerted the police. A few days later, cops brought a man matching the patient's description back the hospital, where he was given anti-psychotic drugs. Only after the man had an adverse reaction to the drugs did anyone figure out he wasn't the patient. The real patient returned to the hospital a few days later.
