Logic

A student failed in law & decided to make a deal with professor.

Sir, do u know everything about law?

Prof: Yes.

Student: If u can answer dis question, i will accept my final marks, if u cant, u have to give me "A".

Professor agreed.

Boy asked: "What is legal but not logical, logical but not legal & neither legal nor logical?"

Prof thought about it for hrs & pondered no answer.

He had to finally give up as he really did not know.

He gave the boy his "A".

The following day, professor askd same ques to his students.

He was shocked when all of them raised their hands.

He asked one student.

He answered:
Sir, u are 65, married to 28 yrs old woman, dis is legal but not logical.

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

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

The professor collapsed...
