Deep thoughts by M

Me: M what are you doing?
M: I am watching Scooby Doo, it calms me.

Babysitter: M that Caillou song is in my head and I can't get it out.
M: Walks over to inspect her head, I don't see it.

Me: M I need to cut your nails.
M: The Incredibles don't need to cut their nails why? They don't have nails?
