I have to admit that it does bug me a little bit that the actual joke about Boo and his nature has kind of been lost over the decades of his memification. I mean, maybe I'm wrong, but wasn't the point that he was just a regular hamster and that "miniature giant space hamster" was obviously Minsc trying to justify why he thinks this ordinary rodent can speak to him? I haven't kept up with the FR canon re. Minsc and Boo, so I imagine it's since become the case that Boo is exactly what Minsc thinks he is - certainly it's the case now, according to this video - but that sort of seems to miss the point!
I'm not mad about it or anything, but it does mean Minsc is retroactively the only sane person in the Baldur's Gate games...
