This is a great show, it may take a little bit to get into it, but once you do, you'll be addicted.

5/5 It's always sunny AND funny in Philadelphia!
  by J. Goff (mountainous region, WV USA)
Set 4 just goes to show that regular joes with a sharp and seriously wicked flare for wit can truly make their dreams come true. The episode where Charlie puts on a play to propose to the waitress makes it worth buying alone, and then you're rewarded with a live version... my eyes water just thinking about it (sniff-sniff). If stupidity is the tuning fork that tickles the ivories of your funny bone (I know that doesn't make sense, but how can I do that when I'm laughing so hard), then 'It's Always Sunny in Philadelphia: Season 4' is for you. BUY IT!

5/5 Great

The funniest show on television but is not for those who are easily offended. There is not one bad episode in the season. Not alot of special features but the ones that are there are funny and worth watching

5/5 One of the funniest DVD!!!!!!
  by Todd A. Richards (Chicago, illlinois)
In this hard economic time, dollars are to hard to come by to be wasted on bad movies or box sets,thus, I was a little hesitant to purchase this dvd set, and some shows just tend to taper off and loose their luster, but Im happy to say that this was not the case!!!!!!!! this season of Its Always SUNNY in PHILADELPHIA,was by far the funniest one yet!!!!,groundbreaking,jaw dropppingly(is that a word?), stupid, funny! you really get your moneys worth and more!!!!!! plus its chopped full of EXTRAS, which really sweeeten the pot, including the DAYMAN PLAY!!!!!, for no extra charge!, how sweet life is!!!!!!

5/5 The Most Hilarious Show Ever!!!
  by Amy Peterson (Peoria, IL)
This show pushes it to the extremes! It is the most hilarious, crazy stuff that makes the FX network originals so great. You definately need to be open-minded and not easily offended to enjoy this show. It is definately worth the money to rewatch the Dayman play over and over again.
