A journalist went to a mental hospital to interview the registrar:
J: How do you identify the patients to recruit for this prominant hospital in the city?
R: we fill the bath tub with water. We keep a bucket, tea spoon and bowl close to the tub. The potential patient is asked to empty the tub as fast as possible....
Now the Journalist jumped to answer...
J: I know..I know...I'll empty the tub with the bucket..it's easy..
R: The normal person will pull out the tub lid to run down the water... Can I arrange your bed close to the window?
