Q: What happened when the nail had a fight with the tire?
　　 A: The nail knocked it flat.
　　
　　当钉子和轮胎打架时会出现什么情况呢？回答一语双关。因为knock it flat既可以指“打倒在地，摆平”；又可以是“刺破轮胎”。不过归根结底还是钉子战胜了轮胎。

Q: A man drove all the way from New York to San Francisco without knowing he had a flat tire. How is that possible?
　　 A: It was his spare tire that went flat.

　　flat tire的意思是“瘪了的轮胎”；spare tire是指“备用轮胎”。如果这个人一路上没换备用轮胎而备用轮胎又瘪了的话，他当然就不会知道了。


Tom: Call your dog off!
　　 Mike: I can't. I've always called him 'Rover' and it's too late to change now.

　　Tom本来是想让Mike把他狗叫走，（Call… off：叫走，把……叫开）；而Mike却开玩笑地说来不及给他的狗改名叫“Off”了。（Call your dog "off"：把你的狗叫作"Off"。）
　　　

Q: How many feet are in a yard?
　　 A: It depends on how many people are standing in it.

　　因为yard和foot都有两个意思，所以这个问句也就有了两种理解方式，1）一码有几英尺？2）一个院子里有几只脚？（yard: 1 码（=3英尺）；2 院子（=court-
yard）；foot：1 脚；2 英尺。）
　　　　　　

Q: Do you know how long cows should milked?
　　 A: Same way as short cows.

　　此问句可以有两种读法：1）...how（怎样）long cows should be milked?和2）...How long（多久）cows should be milked? 而回答问题的人则是按照第一种读法进行回答的。那么应该怎样给个儿高的奶牛挤奶呢？当然和给个儿矮的奶牛挤奶的方法一样了。
