At this time an Army General came along and he loved the dog. He said to Mark Twain, “He is a     . Would you sell him?”
Thinking of his      stomach, Mark Twain thought it seemed to be a good thing and said, “Yes.”
The General asked, “What do you ask for him?”
“Three dollars.”
The General was     and said, “Only three dollars! Are you serious?”
“Three dollars.”
“Very well, since you just want it,” said the General. He gave Mark Twain the  , led the dog away and disappeared upstairs.
In about ten minutes a middle-aged gentleman came along and began to    . Mark Twain asked if he was looking for a dog.
The man’s face had been sad and   , but now it became bright and he answered, “Yes. Have you seen him?”
“Yes. He was here a minute ago, and I saw him follow a gentleman    . I think I can find him for you, if you would like me to     .”
The gentleman said he would pay for the trouble. He asked how much Mark Twain would    .
“Three dollars.”
“Dear me, it is nothing. I will     .”
“No. Three is the    .”
Mark Twain got the General’s room number from the clerk. The door was        and Mark Twain asked the General to give back the dog.
“Why?” asked the General.
“The dog’s owner wants it back.”
“Are you not the owner?”
“No, I am not.”
The General began to shout, but he was too tired to      with Mark Twain. Finally, Mark Twain paid back the three dollars, and led the dog downstairs. He      the dog to the owner and got three dollars for the job.
