Volume I: 1-20 (20 issues)
From the beginning of the series up to issue 20, all comics were drawn in a mediocre Vector program via copy-paste methods. The only recurring characters at this time are John and Mark, our 'heroes' of the series. Jokes about John's hair and his Communist tendencies are abundant in this volume, but die down afterwards.
Volume II: 21-35 (15 issues)
This volume introduces the experimentation of tablet-drawn issues, though they deviate from the 'main' comic format used in Volume I. (There are 'normal' issues still, however.) The Dean is the first extra character to appear in more than one issue (issues 31 and 32), for a two-part story arc, but he is not a definitive recurring character.
Volume III: 3647 (12 issues)
After a hiatus, infrequent issues are produced, introducing a number of changes. While the 'main' comic format returns to the forefront, changes include: header/foot changes, blurring, shading, text nuances, speech-bubble depiction, and a repeated usage of visual experimentation (based on a per issue basis), among other small things. Tablet-drawn comics gradually become the prime method of production.
