Better yet, write your teacher's name and then draw an arrow pointing at the guy lying on the ground.
I did something like this in Graph Comm. We got given 2pt perspective work in 1st year and had no clue what to do. So while everyone started getting it wrong, I drew an isometric view of Mr McGowan getting chainsawed and raped. Luckily, this caught on and I was not found as the original culprit due to most of the class showing off their drawing and claiming it was all on their wit :D
Not a complete happy ending though, since we still haven't been taught 2pt perspective.
