As you can tell from this comic, I drew one, then later decided to replace it with this one. Yeah, I know- it was only day 2 and I was already replacing strips. Well, it doesn't happen again.

To explain: I'd considered drawing a replacement and not mentioning it at all, but I discovered that my artwork had changed sufficiently in the 7 months from when I drew the original that it would be glaringly obvious no matter what. It may be a weak solution to the problem, but as I'm currently working on Zwol comics for next April, I'm beyond worrying about it. Besides- it doesn't happen again.
