体重计
一位妇人看见他的丈夫站在浴室的体重计上，使劲的吸着气,收缩着他的胃。她认为他这么做是为了（称重时）能减轻体重。“这么做是没有用的”她说道。
“当然有用了。”他说“只有这样我才能看见体重计上的数字”。

Funny~

I like the topic "Happiness is the best cosmetic"
But recently ,I'm moody and when I'm upset ,I keep it inside
This joke brings me happiness and remind something about it
I've put on some weight ,I have to lose weight
I'm really ought to start doing something to keep fit .

Scales
A lady noticed her husband standing on the bathroom scale, sucking in his stomach.Thinking he was trying to weigh less with this maneuver, she commented, "I don't think that's going to help."
"Sure it will." he said. "It's the only way I can see the numbers."

体重秤
妻子看见她的丈夫站在洗手间的体重秤上，吸压腹部。想他一定是想用什么方法可以使体重轻一点，她说到：“我不认为那样能有什么帮助。”
“当然有用。”丈夫说到“这是唯一的方法可以让我看到指数。”
