Ever wonder what is in your brain?

Last night, when I climbed into bed and snuggled with Big Dog, he announced in a robot voice that he "needed my brain".
"Don't do it!" warned Mr. Dog.
Too late, Big Dog put his hand on my head and pretended to lift my brain from my skull.
"Thousand Grabioli. Orange. Old Fashioned." pause "and a nut" he says in the same robot voice.
"What? What are you doing?" I asked.
"I am reading your brain." says my son the robot.
"And I have ravioli in there?"
"Yes, grabioli and a nut."
"I see"
He dramatically puts the brain back in place.
"What about your dad?"
"Oh, he already read my brain" he laughs
"So what's in your brain," I ask.
"Ravioli, and a nut."
"Why are there ravioli in our brains?" I ask the robot.
"Go to sleep." says the robot. And that is the end of the discussion.
