Surreal road signage experience

Today as I was driving back from St. Louis, I was confused by road construction barrels into taking an exit near Rolla. I pulled into a driveway, turned around, and was going to pull out and get back on the Interstate, when I noticed a road sign. It was kind of like this one except it was a yellow diamond rather than a red and white triangle, and underneath it was "ROUNDABOUT 15 MPH."

That's not the surreal part, though. The surreal part is that my random-shuffle iPod, plugged into the car radio via the auxiliary port, happened to be playing "Roundabout" by Yes at the time. Seriously.
