Nightman Cometh : My favorite comedic episode of all time

People talk about the popularity of Big Bang Theory, How i met your mother etc etc but nothing compares to what "Its always sunny in philadelphia" brings to the table. I have always loved edgy comedic stuff and nothing gets more edgy than this. This episode is my favorite which is a musical and cannot be more hilarious than ever. How many comedic series can say that a stage drama musical is their best episode. This was even before the "Book of Mormon" probably trey parker and matt stone got inspiration from this group. The following is from their stage drama - re-enaction of their Season 4 finale at Troubadour at West Hollywood. Seeing their fanbase reaction was amazing !!!
