I'm trying to remember where that was. Was it this one? I have a vague memory that there was an earlier one, but can't remember which arc.

Anyway, if that was the one, that's not a last-panel joke, and not just because it didn't happen in the last panel.

Now that I think about it, there was one last-panel joke which showed up later, although not in a plot-significant way. Goblin Dan's All-you-can-eat Hydra Heads shows up as the caterer in Gobbotopia. That was a call back joke and I wouldn't expect anything more significant than that for MaceBook.
