They are too expensive
They have a mind of their own
They replace people's jobs
They beat you at chess
To investigate a murder
To investigate a suicide
To pick up his own robot
To meet Dr. Calvin
In the back
In the head
In the arm
In the leg
That he is married
That is a gemini
That he is a spy
That his left side is robotic
Sonny slams his fist on the table
Sonny attacks him
Sonny hides in the crowd
Sonny draws a picture for him
That humans need protecting from themselves
That the three laws are imperfect
That humans are a danger to robots
That robots want to rule the Earth
When a robot was cooking for his mum
When a package was delivered to his door and he didn't want it
When he chased a robot down the street and ordered it to stop
When he was drowning in the river and he ordered the robot that dived in after them to rescue the little girl and not himself.
