I saw this ages ago in Readers Digest. And I remember almost peeing in my pants!
A first grade girl handed in the drawing below for a homework assignment...
After it was graded and the child brought it home, she returned to school the next day with the following note:
Dear Ms. Davis,
I want to be very clear on my child's illustration. It is NOT of me on a dance pole on a stage in a strip joint. I work at Home Depot and had commented to my daughter how much money we made in the recent snowstorm. This drawing is of me selling a shovel.
So, the moral of the story?
Check your kid's homework before you let them hand it in.
