That's right - as STW reaches 600 lessons, you get not only one comic from your T.A., German Shepherd, you get two. German's facial expression above says a lot - not just 'Why the hell am I in a lab coat again?' and 'I have to do two of these this time?' but also 'There are people who want my teeth? But I need those to eat things with!'

Major thanks again to my students Dan, Karen, Anum, and Skyler for their help in making the comic, and major thanks to all of you for sticking around so long as readers.
