教授与跳蚤(The Professor and The Flea)教授发觉自己并不是街头卖艺的好材料，苦恼之际，他发现了一只跳蚤，这只跳蚤告诉教授能替教授表演赚大钱，但他知道跳蚤有什么野心吗?
There was an aëronaut, and things went badly with him. His balloon burst, hurled him out, and went all to pieces. Just two minutes before, the aëronaut had sent his boy down by parachute - wasn't the boy lucky! He wasn't hurt, and he knew enough to be an aëronaut himself, but he had no balloon and no means of getting one.
Live he must, so he took to sleight-of-hand tricks, and to throwing his voice, which is called ventriloquism. He was young and good-looking. When he grew a mustache and wore his best clothes, he might well have been mistaken for the son of a nobleman. Ladies found him handsome and one young lady was so taken by his charm and dexterity that she eloped with him to foreign lands. There he called himself "The Professor" - he could scarcely do less.
He continually thought about how to get himself a balloon and sail through the air with his little wife. But they still lacked the means to do so.
"That will come yet," he said.
"Oh, if only it would," said she.
"We are still young people," he said, "and I'm a Professor."
"Crumbs are also bread!"
She helped him all she could, and sat at the door to sell tickets for his entertainments. In the wintertime this was a chilly sort of pleasure. She also helped him with one of his acts. He would put her into a table drawer - a large table drawer - and she would creep into the back drawer. From in front she was not to be seen, and as far as the audience was concerned she was invisible. But one evening, when he pulled out the drawer she was invisible to him too. She was not in the front drawer, not in the back one, and not in the whole house. She was nowhere to be seen or heard, and that was her contribution to the entertainment.
She never came back. She was tired of it all, and he became tired of it too. He lost his good humor and could not laugh or make jokes, so people stopped coming to see him. His earnings fell off and his clothes wore out, until at last all that he had was a large flea, an heirloom from his wife; that's why he liked it so well. He trained the flea and taught it to perform - to present arms, and to fire off a cannon. Of course it was a very small cannon.
The Professor was proud of the flea, and the flea was proud of himself. He had learned a thing or two, and had human blood in him. He had been to the largest cities. Princes and Princesses had seen him and given him high praise, which was printed in the newspapers and on the billposters. He knew he was a famous flea who could support a Professor, yes, a whole household.
Proud he was and famous he was. Yet when he and the Professor traveled they went by fourth-class railway carriages, which took them along just as quickly as those of the first-class. They made a secret pledge to each other that they would never separate. Neither of them would marry. The flea would remain a bachelor and the Professor a widower. That made them even.
"Where one has the best luck," said the Professor, "one ought not go back a second time." He was a student of human nature, which is a science in itself. At length he had traveled through all countries except the savage ones, and to those he decided to go. There they eat Christian men. The Professor knew this, but then he was not much of a Christian, and the flea was not much of a man, so he thought they might venture successfully into the wilds, and make a lot of money.
