2. Your little Tommy wants a slingshot for his birthday, but you shouldn’t give him one. If you do, next he’ll want a B-B gun. Then a 22 rifle. After that it will be a high powered rifle, and then an Uzi and an AK-47. Soon he’ll want a bazooka and after that an antiaircraft gun. In no time your home will become an armory.
