WTF?

I was on campus a week or so back to take a midterm. On the way in, I drove past the backlit, movable-letter sign announcing upcoming campus events. All fine.

On the way out, I literally stopped in the middle of the street to stare at the back of the sign. It said:

ZOMBIES

ARE

COMING

I repeat, WTF? (I tried to take a picture, but my crappy camera phone couldn't deal with the backlight.)
