The Simpsons

We know we shouldn't, we know that we have been told not to, but we can't help it -- we're totally having a cow, man!  This is episode 500 of the ridiculously long-running animated comedy.  The show has, understandably, morphed and changed through the years, but it still somehow manages to put out a whole lot of funny over the course of the season.  We have to believe that tonight, for episode 500, we're going to be treated to something really and truly special... you know, like Homer creating an invention and then screwing it all up, or Bart getting in trouble at school, or Marge deciding she wants more in life than to just be a mom.
