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."
