Grey hair problem

A curios child asked his mother: "Mommy, why are some of your hairs turning grey?"

The Mother tried to use this occasion to teach her child: "It is because of you, dear. Every bad action of yours will turn one of my hairs grey!".

The child replied innocently: "Now I know why grandmother has only grey hairs on her head."

Hahaha, classic jokes.
Laugh up, its a beautiful monday! =D
