英语幽默笑话：开个玩笑

A small boy leading a donkey passed by an Army camp. A couple of soldiers wanted to have some fun with the lad(少年，小伙子) .
What are you holding onto your brother so tight for, sonny? asked one of them.
 
So he won't join the army, the youngster replied without blinking an eye.
 
一个小男孩牵着头驴子穿过部队营房。两名士兵想跟小家伙开个玩笑：
 
小孩，你把你哥哥牵得这么紧干什么?
 
这样，他就不会去参军了。小家伙眼都不眨地回答道。
