conversations in nursery

So in nursery today, the coloring activity was really advanced: one option featured a boy, the other a girl. So our conversation went a little like this:

Shauntel: "Now raise your hand if you're a boy."

Four out of five hands raise. Shauntel hands out the boy handout to the boys, including the one who didn't raise his hand.
A: With a look of disgust, "Hey, I'm not a boy!"
S: "You're not? What are you then?"

A: Completely serious, "A robot."

DUH.
