SLEEPY

Billy: "Rene, I have a riddle here. Can you guess?"

Rene: "Really. Okay... try me."

Billy: "Here it is. Which part of your body does support our head?"

Rene: "Hey, that's easy. 'Neck', of course."

Billy: "A a... wrong guess! Try again!"

Rene: "No way! 'Neck' is the right answer. Or maybe, neck bone?"

Billy: "No, no... the answer is 'EYES'."

Rene: "How come?"

Billy: "Well, you see the man in the picture? No matter how strong is your neck, if your EYES are sleepy, you won't be able to support your neck." (Xixixixixixixixixixi..................:P)
