After having failed his Exam in "Logistics and Organization", Danny goes
and confronts his Lecturer about it.
Danny: Sir, Do you really understand anything about the Subject?
Professor: Surely I must, otherwise I would not become a Professor!

Danny: Great, Well then I would like to ask you a Question. If you can
give me the correct answer, I will accept my marks as is and GO. If you
however, do not know the answer, You must then give me an "A" for the Exam.
Professor: Okay, it's a deal. So what is the Question?

Danny: What is legal, but not logical, logical but not legal, and neither
logical nor legal?

Even after some long and hard consideration, The professor can't give Danny an answer, and therefore changes his Exam mark to "A" as agreed. Still puzzled, the professor later calls on his best student in his class, Sihle, and asks him the same question.

Sihle immediately answers, "Sir, you see, you are 63 years old and married to a 35 year old woman, which is legal, but not logical. Your wife has a 25 year old lover, which is logical, but not legal. The fact that you've given your wife's lover an "A", although he should have really failed, is neither legal nor logical."

PROFESSOR FAINTED!!!!!!!!!!
