I really don't think this needs much in the way of comments. I'm sparing you the more graphic photos from this lecture. Yes, it's barely 8:15, and I just ate breakfast. I suppose it's good practice. Also, notice the hand drawn nature of the slide... yet again.

For some reason, professors seem to LOVE showing students the "first figure I ever made!" We, the students, realize this is a work of art, a thing of great pride, and a bit of a rite of passage for our professors. Yet, what these professor's don't seem to understand is that the "first figure" probably isn't very good. It was probably hand drawn, or roughly sketched with a mouse in powerpoint. It's probably not particularly well labeled (because once you've finished the sketch, you're sick of the figure), and it's probably just a teensy-tinsy bit out-dated.
Still, I think we've had at least 4 of them to-date... and counting. :)
