Maybe some of you who have been fans of MI for a long time know the answer to this. But being a newcomer to the series (heard of it through TT) I was rather taken aback by the strangeness of his name. True, it grows on you, but my initial reaction was something like, "Seriously? How are you supposed to take a name like Guybrush Threepwood seriously?" And then I played the game and realized you're not!
But I'm still curious, does anyone know how they came up with it? I've never heard of anything at all like it.
