I'm not a huge fan of abstract artwork. Not that I don't think it's interesting or that it doesn't have anything important to say, but I prefer a little more clarity when it comes to the subject of an artwork. Also, I enjoyed drawing that weird painting in the second panel.
Shoot. I just realized I forgot to draw Billy's mustache in the last panel. Maybe no one will notice. Well, I just wrote it so now everyone will notice. Let's just say he took it off and put it on the painting. That's actually funnier, I think.
