Passing An Exam
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 five years.

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!"
