Donny在北京学汉语，她的中国朋友要是遇到了不知道用美语怎么说的词，就会来请教他。今天是吴琼要问的是：挂羊头卖狗肉。
Donny: Hey 吴琼, 你看，买这个可以赢200块现金奖！
WQ: 200块?！ 哪有这种好事？I mean....It's too...too 什么来着？
Donny: It's too good to be true!
WQ: 没错，It's too good to be true. 哪有这种好事? 你仔细看看，抽奖细则里一定有什么附加条件。Donny, 这种附加条件英文怎么说？
Donny: It's called "catch." You can say: It's too good to be true. What's the catch?
WQ: Oh, catch, C-A-T-C-H, catch. What's the catch? 就是“有什么附加条件”？
Donny: 对。Now 吴琼, tell me how I can win this.
WQ: 你就别想了! 你看，你要先花五百块买这件产品，然后再去抽奖，中奖率千分之三！这根本就是挂羊头卖狗肉！
Donny: 挂羊头卖狗肉！这种说法好，英文里叫：false advertising!
WQ: 假广告？没错，就这意思。你别被忽悠啊！
Donny: I can't believe I almost got bamboozled!
WQ: Bamboo...竹子什么?
Donny: 是 Bamboozle, B-A-M-B-O-O-Z-L-E, 就是骗人。
WQ: 换句话说，Bamboozle 就是忽悠别人喽?
Donny: Exactly. I almost got bamboozled. 我差点就被忽悠了。
WQ: 是啊，不是说 There is no such thing as a free lunch. 天下没有免费的午餐嘛!
Donny: Yea, you're right! Let's see what you've learned today.
第一，哪有那么好的事是 it's too good to be true;
第二，隐含的附加条件是 catch, as in "What's the catch?"
第三，挂羊头卖狗肉是 false advertising;
第四，忽悠是 bamboozle!
