Joke of the day: chintu and the professor

Chintu failed in the final Law Exam & decided to make a deal with the Professor.
Chintu: Sir, Can I ask you one question?
Professor: Yes.
Chintu: If you can answer this question, I will accept my final marks, if you cant, you will have to give me an "A" grading.
Professor agreed.
Chintu asked: "What is legal but not logical, logical but not legal & neither legal nor logical?"
Prof thought about it for hrs & pondered but couldnt think of an  answer. He had to finally give up as he really did not know the answer.
He gave this boy an "A" grading as promised.
The following day, Professor asked same question to his students.
He was shocked when all of them raised their hands.
He asked one student. He answered:
Sir, you are 65, married to a  28 yrs old woman, this is legal but not logical.

Your wife, is having an affair with a 23 year old boy, this is logical but not legal.

Your wife's boyfriend has failed in his exam & yet you have given him an "A", this is neither logical nor legal. .

Professor fainted....
