Poor Professor Witzig. I believe this was the first strip where I used curved lines like the ones in the second panel to indicate movement -- that's something I've been doing for a long time, but I was hesitant to put it in this comic strip, because I'd way overused them in previous comic strips (and no, you don't want to see those). After awhile, though, I decided this strip needed the lines, so I drew them in. I've used them a few times since, but not that often.
