Oh, okay, so the dojo master is a sexist. I thought it was some kind of more subtle jab at society or something. Or it could be as well still, I just didn't know the original context which makes it fairly concrete.
Coding it in as an item could be part of that joke or statement or whatever. I know that if I was making a game I would do something like this, coding an implied item to be an actual item (in the in-game sense), even if I never intended it to be used.
Well, thinking too deep on this now.
Aren't there web sites that catalogue all sorts of unused/cut content? Even though I don't recall seriously perusing it, I recalling hearing about
The Cutting Room Floor but now that I Google it I can't tell if it's merely down or if it's blocked at work. Anyway, if you're the first one to find this out, while thanks for sharing it here, it might be a tidbit worth sharing with them (or other game historians) too.
