No, really, they're not. They are images of a couple of snowballs. And if Monsieur Magritte was still around, he'd tell you that himself.
I was walking at the park in sunny, 65 degree weather (that's 18 degrees for my Celsius friends), and rounded the path to see the grass littered with large, random snowballs. It was the most surreal, silly sight I'd seen all week. Seriously. I had to sit down on a bench because I was laughing so hard. But then I took this photo to share the surreal world of Knoxville with y'all. Only a little man in a black greatcoat and a bowler hat could make it more complete.
This also told me a lot about my fellow Knoxvillians. Apparently we're consistently two snowballs shy of a snowman.
