Wow, that's a reference from a comic more than 180 S-sub-Not's ago. Just one of those odd details that
has to remain true to stay consistent with other things.
The comment on the actual making of this, is that the lockers are pretty extranious, but do add a bit of a feeling of space more necessary now than seemed necessary before.
And also that This comic was writen and drawn and worded with the panels in a different order, only to be rearanged at the last minute on a whim, though I think that it benifited from that.
