Yeah, it's actually the one question I wish was asked in recent interviews with Ron, but I'm partially afraid his answer would be "It didn't actually mean anything, it was nothing more than a joke at the time." lol
All that being said, this discussion has reminded me again why I love this game and this series so much. So many layers to it, especially in Return. Over a year later, and I'm still constantly thinking about how everything fits together. In other cases, that would be frustrating, but for these games, it's great because there is enough evidence to support multiple theories. Monkey Island is really the one series I know that wholly embraces head-canons in such a unique way.
