So, today in art (Flash back)...Me:  Everyone in this line stop moving.  Where are these crayons coming from?  (Someone has taken a box of crayons, I can hear them dropping on the floor, and I am now following the trail of crayons to the guilty student.)  Me:  Do you have some of my crayons?  Student:  No.  Me:  Umm...They are falling out of the hole in your pocket...right now...while we are speaking.  Student:  I don't know where these crayons came from.  Me:  Maybe your mother does.  Let's go call her.
