Henry Leech was a good salesman. He sold lots of products. After a new kind of vacuum cleaner (真空吸尘器) was produced by his factory, he was sent to the countryside to sell it.
He drove out of town and stopped at a farmhouse. He knocked on the door and the farmer's wife opened it. Henry started into his speech immediately.
"Madam, how much time do you spend cleaning the floors?" "A lot of time. This is a farm and things get dirty quickly," said the woman.
"And how much time do you spend beating the carpets(地毯)?" asked Henry.
"A lot of time. My dog lays on them and it always makes a mess on the carpets."
"Well," said Henry, "this is your lucky day." Henry showed her his vacuum cleaner and said, "You can clean the house in 5 minutes with it."
The farmer's wife didn't look interested, but Henry still took out a big bag of dirt(尘土). He opened it and threw it all over the floor. The farmer's wife was very surprised. Before she could speak, Henry said, "Madam, if this machine doesn't pick up every last piece of dirt, I will eat all of it!"
The farmer's wife looked at Henry and said, "WELL, I WILL GET YOU A SPOON. WE HAVE NO ELECTRICITY(电)."
