I overheard this in the room I was working in today.
Teacher's Aide: So now we have to do this page on clocks. You know clocks?
Little Zombie: Oh yeah. That's soooooo easy!
Aide: Okay! So what's this hand on a clock called?
LZ: The hour hand.
Aide: Good. And this one?
LZ: Ummm.... the second hand?
Aide: No, the second hand is this one. The skinny one. What is this hand called if it's not the hour hand or the second hand?
Aide: It's the one in the middle. It starts with an M....
LZ: OH! The middle finger!
