Caught this one second-hand but still have to add it as it's one of my fave kidlets.

Nico (2nd grade, autistic, hilarious): *obsessing over a train on his desk*
EA: Nico, listen to your teacher, she's talking to you.
Nico: *not listening*
EA: Listen to... what's your teacher's name?
Nico: Mrs. BORE-ing!

I love that kid.
