Ha haa, love it. Without all the the's, you would have no job, editorial staff. Though I've never had an editor. But I can surely relate to the problem. I've seen some of mine succumb to or or and to to and a few others. And as for the brain, I don't know how many times I write something I like that is a bit off-kilter, and I re-read it, and time after time, my brain reads it differently than the page. So I usually succumb. Figuring that if I (in bold, no way to do that here) can't read it correctly, the public certainly won't. But I LIKE it that way...whinge whinge. This whole writing thing is a fun, maddeningly odd endeavour. Though I think they should make 'double wording' part of spellcheck.
And nincompoop is one of the best descriptors ever. I don't use it enough, even though I was called one many times growing up.
