This episode is pure comedy gold! When you thought the show couldn't be any funnier the next one tops that. All other sit-coms these days use the same jokes over and over but this show ads something that hasn't been shown before. I would call it more smart comedy because there are a lot of movie/series/music references that is hilarious if you gets them.
Each characters have their own charm and NONE of them gets boring. I haven't seen this since the Seinfeld era that was many years ago.
The plot with Jeff turns down the group but later returns in the end has been played out a little bit but other than that the manuscript is amazing.
Best comedy show this decade!
