I have been reading Dennis the Menace for — well not my entire life. There was a stretch for the first couple years when I wasn’t able to read. But past that, I’ve been reading Dennis the Menace my entire life and it’s just this week I find out Dennis has a middle name? I knew he had a last name, although it took me long enough to settle on “Mitchell” that I would have been in trouble on a game show. But a middle name? That isn’t “The”? Yes, if you proposed that his name was “Dennis The Mitchell” I would have to accept you were right.
Anyway, Wikipedia offers that his full name is Dennis Roger Mitchell, though it doesn’t give a source. The comic strip, I suppose. Also apparently the strip takes place in Wichita, Kansas, if you believe Wikipedia. Wikipedia also claims that Wichita, Kansas, is on the Arkansas River. As far as I know that’s right, so maybe we can trust Wikipedia about this Dennis “Roger” Mitchell thing too. I don’t know.
