calmly motionless, for coming across the field toward him were two human beings.
He turned to face them, and they altered their course to meet him. A moment before, they had been talking loudly. He had heard their voices. But now they were silent. They had the look that Andrew associated with human uncertainty; and they were young, but not very young. Twenty, perhaps? Andrew could never judge human age.
"Would you describe to me the route to the town library, sirs?"
One of them, the taller of the two, whose tall hat lengthened him still farther, almost grotesquely, said, not to Andrew, but to the other, "It's a robot."
The other had a bulbous nose and heavy eyelids. He said, not to Andrew but to the first, "It's wearing clothes."
The tall one snapped his fingers. "It's the free robot. They have a robot at the old Martin place who isn't owned by anybody. Why else would it be wearing clothes?"
"Ask it," said the one with the nose.
"Are you the Martin robot?" asked the tall one.
"I am Andrew Martin, sir," Andrew said.
"Good. Take off your clothes. Robots don't wear clothes." He said to the other, "That's disgusting. Look at him!"
Andrew hesitated. He hadn't heard an order in that tone of voice in so long that his Second Law circuits had momentarily jammed.
The tall one repeated, "Take off your clothes. I order you."
Slowly, Andrew began to remove them.
"Just drop them," said the tall one.
The nose said, "If it doesn't belong to anyone, it could be ours as much as someone else's."
"Anyway," said the tall one, "who's to object to anything we do. We're not damaging property." tie turned to Andrew. "Stand on your head." "The head is not meant-" Andrew began.
"That's an order. If you don't know how, try anyway."
Andrew hesitated again, then bent to put his head on the ground. He tried to lift his legs but fell, heavily.
The tall one said, "Just lie there." He said to the other, "We can take him apart. Ever take a robot apart?"
"Will he let us?"
"How can he stop us?"
There was no way Andrew could stop them, if they ordered him in a forceful enough manner not to resist The Second Law of obedience took precedence over the Third Law of self-preservation. In any case, he could not defend himself without possibly hurting them, and that would mean breaking the First Law. At that thought, he felt every motile unit contract slightly and he quivered as he lay there.
The tall one walked over and pushed at him with his foot. "He's heavy. I think we'll need tools to do the job."
The nose said, "We could order him to take himself, apart. It would be fun to watch him try."
"Yes," said the tall one, thoughtfully, "but let's get him off the road. If someone comes along-"
It was too late. Someone had, indeed, come along and it was George. From where he lay, Andrew had seen him topping a small rise in the middle distance. He would have liked to signal him in some way, but the last order had been "Just lie there!"
George was running now, and he arrived on the scene somewhat winded. The two young men stepped back a little and then waited thoughtfully.
"Andrew, has something gone wrong?" George asked, anxiously.
Andrew replied, "I am well, George."
"Then stand up. What happened to your clothes?"
"That your robot, Mac?" the tall young man asked.
George turned sharply. "He's no one's robot. What's been going on here."
"We politely asked him to take his clothes off. What's that to you, if you don't own him."
George turned to Andrew. "What were they doing, Andrew?"
"It was their intention in some way to dismember me. They were about to move me to a quiet spot and order me to dismember myself."
George looked at the two young men, and his chin trembled.
The young men retreated no farther. They were smiling.
The tall one said, lightly, "What are you going to do, pudgy? Attack us?"
George said, "No. I don't have to. This robot has been with my family for over seventy-five years. He knows us and he values us more than he values anyone else. I am going to tell him that you two are threatening my life and that you plan to kill me. I will ask him to defend me. In choosing between me and you two, he will choose me. Do you know what will happen to you when he attacks you?"
The two were backing away slightly, looking uneasy.
George said, sharply, "Andrew, I am in
