This strip is #2 in the original run dating from my university days.

I have to state that most of this artwork was generated at top speed, because my time was at a premium back then. In retrospect, I should have chosen a simpler style, because my characters go (seriously) off-model all the time. Just looking at this particular strip makes me shudder. I just want to shout “Get a smaller forehead!”

The gag here was intended to become a recurring joke where Puck talked to her brain. I never actually revisited the concept after this.
