Check out these folks who covered their house in sheet metal!!!
Now he has something to strive for (look at the "protection" he recently installed behind his garage in this picture... and I think he may have installed some more recently).
I'm very tempted to print it out and put it on his door, but that would require actually going near his house and I'd rather not do that.
Then again, with my luck, he knows them from online and they're the ones who got him thinking I was a narc in the first place.
