Just so the hilarity of this drawing isn't lost in translation, I'll give you the run down as it was told to me by the student who drew it.

First, there is a crazed snowman with an axe. He is going to cut down the Christmas tree. But, wait! There is a sign that clearly states, "NO cutting trees! You'll go to jail." This explains why there is a police helicopter hovering above the scene.

(And you all thought that 8 year olds were sweet and innocent!)
