Just joking...

I paraphrased this a bit to make it on topic:

A ninth grader had received a failing grade on her test paper and went to her teacher to ask, Mrs. Johnson, can you answer any question?
Mrs. Johnson replied, Of course, otherwise I would not be your teacher.
Great, then, I would like to ask you a question. If you can give me the correct answer, I will accept my failing mark as is and go. If, however, you do not know the answer, I want you to give me an A for the test.
Okay, she agreed. Its a deal. So, whats the question?
The ninth grader asked, What is legal but not logical, logical but not legal, and neither logical nor legal?
Her teacher sat for a few moments of consideration and then gave up, not giving her student an answer. The ninth grader got an A for her test.
Afterwards, Mrs. Johnson called on her best student and asked her the same question. Her best student immediately answered, Mrs. Johnson, you are 63 years old and married to a 35 year old man which is legal but not logical. Your husband has a 14 year old lover which is logical but not legal. The fact that you have given your husbands lover an A, although she really should have failed, is neither legal nor logical.
