A greedy man went shopping for shoes, hoping to find a bargain. To his surprise, the shopkeeper said, "You can take any pair of shoes here for free, but on one condition: you must not speak for three days."
"What a deal!" the greedy man thought. Believing this was a stroke of luck, he picked out a pair of shoes worth 500 yuan and headed home in silence. When his wife asked how much they cost, he remained silent. No matter how many times she asked, he did not utter a word.
His family grew worried and called for a doctor. When the doctor questioned him, the man bit his lip and kept silent. The doctor was baffled, thinking it was an incurable mysterious illness, leaving his wife terrified.
When the three days were up, the shoemaker came to the house. After chatting with the wife for a while, he entered the room alone and said to the greedy man, "The time is up; you may speak now." With that, the shoemaker took his leave.
The greedy man excitedly shared the story with his wife, boasting, "This is wonderful! I got a pair of 500-yuan shoes just by staying silent for three days!"
The wife glared at him and exclaimed, "What? The shoemaker just said he could cure mutes, and he already took one thousand yuan from me!"
一个贪心的人上街买鞋，心里想着能捡个便宜。不料，店主却说：“我这里的鞋，一分钱不要，随你挑。但有个条件，就是你在三天之内不能说话。”
这太划算了！贪心鬼觉得这简直是捡了大便宜，于是挑了一双价值500元的鞋，一言不发地回了家。妻子问他这鞋多少钱，他始终保持沉默；妻子再三追问，他还是不开口。
家人见状十分焦急，赶忙请来医生。医生询问他的情况，他也咬牙坚持不说话。医生也感到束手无策，认为这是一种无法医治的怪病，妻子的心情更是跌到了谷底，吓坏了。
三天期限一到，鞋匠来到他家，先是与妻子聊了一会儿，随后单独走进屋子对贪心鬼说：“时间到了，你可以说话了。”说完，鞋匠便告辞离开。
贪心鬼迫不及待地把这件事告诉妻子，眉飞色舞地炫耀道：“太棒了！仅仅三天没说话，就白白得到了一双价值500元的鞋子！”
妻子听后，瞪大了眼睛说道：“什么？刚才鞋匠说他能治哑巴，已经从我这儿拿走了一千元了！”
