"Psychiatric Exam" joke
The head psyciatrist at a mental institution is preparing to give three patients an exam. If the patients pass the exam, they will be free to leave the hospital. Should they fail, they will remain institutionaized for an additional five years.
The doctor leads the three patients to a diving board overlooking a pool that doesn't contain any water and asks the first patient to jump.
The first patient jumps off the board into the pool and breaks both arms.
The second patient jumps and ends up breaking both legs.
The third patient looks over the side of the board and flatly refuses to jump.
"Congratulations!" You are now a free man," says the doctor. "Just tell me why you wouldn't jump."
"I can't swim, doc," replies the third patient.
