Akpors’ logic

After writing the most awful exam in his life, Akpors offered his Professor a deal to save his grades:

“If you can answer just one question, I will accept my final marks, if you can’t, you have to give me an ‘A’.”
The Professor agreed.
Akpors asked: “What is legal but not logical, logical but not legal and neither legal nor logical?”

The Professor thought about it for hours and pondered but found no answer. He finally had to give up as he really did not know and he gave Akpors an “A”.

The following day, professor asked same question to his students.
He was shocked when all of them raised their hands. He picked one of them.

The student answered: “Sir, you are 65, married to 28-year-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”, this is neither logical nor legal.”

The professor fainted!
