Speaking of inappropriate humor and making fun of just about everything you shouldn’t, we’ve got a nice little surprise for you today, courtesy of the folks over at FX. They were kind enough to send over two brand new behind the scenes videos from the upcoming fourth season of the hit show “It’s Always Sunny in Philadelphia.” As you may have heard, this is a show that is a favorite around the FSR offices, as we too are very much in tune with their brand of humor. It is irreverent, depraved and often idiotic — and that’s why we like it.

Have a look at the two behind the scenes features below.

As you can see, we have plenty to look forward too when “It’s Always Sunny” comes back to FX on September 18. And just in case you missed it, don’t forget to check out the gangsta rap video and Comic-Con footage that I posted a few days back. That can be found here.
