Comma Coma

I've been going through those proofreading notes that I told you about yesterday. I regret to say that it turns out I know exactly as little about commas as I did during the preparation of my last book. There is one very specific comma mistake that I make over and over, but I will never tell you what it is! It's too sad. I also discovered, thanks to the copy editor, that the phrase "expertly piloted into my anal cavity by remote control" should have more properly read, in context, "expertly piloted by remote control into my anal cavity." Live and learn!
