You've may have seen "the wave" at football games before.  It was my son's favorite part of the game when I took him to his first NFL game.  But have you ever seen a stadium doing "the roller coaster"?  It's similar.  My question is, "Doesn't anyone just watch football anymore?" and "How bad was this team getting beaten?"
