-----------------------------A Student failed in law-----------------------

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 asked same question
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..
