[Joke]企鹅 Penguin

为什么企鹅的身体前面是白白的~可是后面是黑黑的呢？
Why the front body of the penguin is white, while the back is black color?

答案： 因为企鹅的手很短~洗澡时，这能洗到前面，后面，就因为手短，洗不到~
因为洗不到背后，背后就肮肮脏脏的。。久而久之，就变黑黑了~
Answer: Because penguin's hand is very short, so when taking bath, only can wash the front, can't wash the back. so slowly is becomes black...
