haven't heard the Weird Al version (although I plan to once I get home now) but if it's what I suspect it is I can see why it would edge out the Madonna version. I suspect it's all about disillusionment as well.

What do we do when we discover the world isn't the bright, shiny place we were told it was? Sometimes we resign ourselves and accept it, sometimes we get out the polish and rags and get to cleaning it up, and sometimes we look a little to the left or right and see things aren't exactly as we thought they were but they are far from dismal. Each response has it's appropriate time and place. When that is we have debated amongst ourselves as long as there have been people.
