This happened today.....
First grade teacher gave her class an assignment - draw a picture of your face.
A little girl handed in her drawing.
Teacher:  "The assignment was to draw a picture of your face. Now does this look like your face?"
Student:  "Yes."
Teacher: (Sighs) "Is your face purple?"
Student: "It is when I'm constipated."
As an add on to this post, I have to relate the following, also true.
I was sitting on a bench the other day, and a young woman walked by. I couldn't help noticing her T-shirt, the back was emblazoned in very large letters LIVING IN THE NOW.  In the center of the O were the numbers "2014".  I'm still laughing at this one.
