Clevorbot: Are you a robot?
Me: No.
Clevorbot: Are you sure?
Me: Positive.
Clevorbot: What if you don't exist?
Me: Then I'm a dream.
Clevorbot: That's right, very good. You get a cookie and a crayon.
Me: Can I have just the cookie?
Clevorbot: Yes. Here it is.
Me: Ew, it tastes horrible!
Clevorbot: What tastes good?
Me: Your mom.
