Real life Pacman!

I was sitting in the library, trying to decide on a topic for today's story.  Suddenly, in ran two juniors, covered in paper.  I was confused at first, and slightly annoyed that they had interrupted my work-space.  However, as they turned to run past me, I noticed that one was dressed in yellow paper, cut to that tell-tale sliced pie shape.  The girl behind was a red ghost. I burst out in laughter, realizing that I had found my story topic!
