Three patients in a mental institution prepare for an examination given by the head psychiatrist.

If the patients pass the exam, they will be free to leave the hospital. However,

If they fail, the institution will detain them for seven years.

The doctor takes the three patients to the top of a diving board overlooking an empty swimming pool, and asks the first patient to jump.

The first patient jumps head first into the pool and breaks both arms.

Then the second patient jumps and breaks both legs.

The third patient looks over the side and refuses to jump.

"Congratulations! You're a free man. Just tell me why didn't you jump?" asked the doctor.

To which the third patient answered, "Well Doc, I can't swim!"

Empty the Bath Tub

The health minister is visiting a psychiatric ward. He asks the head of psychology dept. "How do you determine if a patient is cured?"

The Psychologist explains: "We take them to the bath tub which is filled with water, hand them a spoon and a cup and ask them to empty the bath tub."

"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."
