The health minister Mr. Amadasa is visiting a psychiatric ward.
He asks the head of psychology, "How do you determine if a patient is cured."
The psychologist explains:
"We take them to the bathtub, which is filled with water, hand them a spoon and a cup and ask them to empty the bathtub."
"I see," says the health minister, "The cured person would choose the cup because it`s bigger, and would empty the tub faster."
"Actually no," replies the psychologist, "A normal person would simply pull the plug."
