I know the "IOA = Literature Theme" discussion was a page or two back, but I'll just say that I've been going to the park for years and didn't know until a few months ago, when I read it on here, that this was the case. I see it now, but I never made the connection.
Also, I might add, Dudley Do-Right is not a literature/comic book character. It started as a segment on the Rocky and Bullwinkle TV show. So they violated their own theme from the beginning, and I don't think we should let the literature-based rule limit the possibilities.
