Here's a list of the top 50 greatest TV shows, a topic that is endlessly arguable, however this particular list falls flat on its face from the start of the gun because it does not include It's Always Sunny in Philadelphia which immediately invalidates the list and deprives it of any authority. MRod has spoken. Netflix, Tivo, Surfthechannel (hint hint), rent--I don't care what method you prefer, but see the most hilarious show on television It's Always Sunny in Philadelphia RIGHT NOW and prepare to watch what Seinfeld could have been if it had endeavored for greatness and excellence.
