"Sir, do you know everything about law?"
Prof: "Yes."
Student: "If you can answer this question, I will accept my final marks, if you cant, you have to give me "A" Grade."
Professor agreed.
Boy asked: "What is legal but not logical, logical but not legal and neither legal nor logical?"
Prof thought about it for hours and pondered no answer.
He had to finally give up as he really did not know.
He gave the boy his "A" Grade.
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 28 years 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 and yet you have given him an "A" Grade, This is neither logical nor legal."
