Stupid question, I know. I've done some internet searching looking into this . . I see a movie about a Nigerian Prince, but it's metaphorical and looks like a drama. I see some sort of comic on Amazon, but I don't care about that. Then I see a story from Clarkesworld Magazine in 2016. ( http://clarkesworldmagazine.com/okorafor_11_16/ ) It's not the type of thing I'm after . . . I think . . . so that should be okay. I was going to write a short where the Nigerian Prince shows up with some other spam-email characters to save the day, like they really do exist and they are our last hope, but I feel like I'm stealing the idea, and I can't do that. But I'm not sure . . . I once picked up a magazine in Barnes and Nobel and was thumbing through it, and I THOUGHT I saw this story/plot, BUT, there's a chance that I was looking at that 2016 Clarkesworld (it was about at that time I had the idea), and the story I imagined that I saw hasn't really been written. And that means I need to do it! What I was looking at seemed like some sort of comedy about the Nigerian Prince. Has anyone ever read something like this? I don't want to waste time writing something that won't be published because it's already been done. An aside: I once had an idea for Nixon vs. the supernatural, where he would have been the ultimate anti-hero, but then I saw this ( https://www.amazon.com/Crooked-Austin-Grossman/dp/031619851X ), which was exactly the type of thing I was going to do. I still think mine would have been funnier. Nixon was going to fight Sacco and Vanzetti in a duel for our souls. He must cast himself out of the White House to complete the ritual. But anyway, I would never have been published with a duplicate idea. So much for that.
