In which Home Depot plays an April Fool's joke on me in December

I was swapping out outlets and covers at the rental property today, among many other messy things (maybe I'll post that next...).  I got to this plate cover and, in because I was in screwing auto pilot, just putting screwdriver to screw without really thinking about it, was momentarily incredibly confused.  I'm glad one of the outlets was wired wrong initially so I could over it with a flat plate and had an extra outlet cover available.
