Robot

Andy- You're not even really a human, you're a robot.
Cj- I'm a human being! I'm not a robot.
Andy- You're a robot we just never told you. Mom wanted to have another kid but didn't want to have to have him the real way so she just had a robot made.
Cj- How could I have been a robot all this time and not even known it?
Andy- You didn't know it because when someone is a robot, they have to be told at the right time. And now is the right time, because I just told you.
At this point, Cj is starting to get a little convinced and looks at me with worry and questions in his eyes.
Me- Cj you are not a robot, I promise.
Andy- Don't listen to Mom, she's evil. She didn't even tell you that you were a robot.
