if you drink ，肚里就不会长虫了

A father was trying to teach his son the evils of alcohol.
He put one worm in a glass of water and another worm in a glass of whiskey. The worm in the water lived, while the one in the whiskey curled up and died.
"All right, son," asked the father, "What does that show you?"
"Well, Dad, it shows that if you drink alcohol, you will not have worms."

一位父亲打算让自己的儿子知道酒精有多么可怕。
他把分别把两只虫子放到一杯清水和一杯威士忌里做对比。
清水里虫子安然无恙，结果威士忌里的虫子蜷缩了几下就挂掉了。
"所以，儿子啊，"父亲问道，"得出什么结论？"
"恩，这说明，你只要喝酒的话，肚里就不会长虫了！"
