Homework doodles

Ever since the ninja-versus-ogre incident, I’ve been getting more and more pictures on homework.

For example, here is a student who expresses his appreciation of the newfound technique of integration-by-parts:

I’m not sure what to make of the impotent “Bang” coming out of the tank though…

I also require that students indicate when they’ve used L’Hospital’s Rule, usually by an “LH” or by a whack with the “L’Hospital stick”, but this guy even put on a L’Hospital batter to go with it.

All I want to say is that that is one well-drawn batter, even if he does look a bit like Disney’s Robin Hood.
