Netflix fans are constantly stumbling across the comically dark show considered to be the longest-running live-action sitcom ever made.

It’s Always Sunny in Philadelphia, which has been on the air for an incredible 16 seasons, has debuted a total of 170 episodes during its impressive run.

The comedy show, which is packed with rude jokes and pitch-black humour, first aired on FX back in 2005 and has already been renewed for another two seasons at least.

The concept was thought up by Welcome to Wrexham’s Rob McElhenney, and co-created with fellow writers and co-stars Charlie Day and Glenn Howerton.

The three friends appear together in the sitcom alongside Hollywood icon Danny DeVito - and Kaitlin Olson, who wed McElhenney after filming the show’s fourth season.

Even though the show has been around for almost 20 years, it continues to pick up fans on Netflix all the time thanks to its hilariously dysfunctional characters and bizarre storylines.

The sitcom is deeply satirical with a dark and self-deprecating tone, and one of its best strengths is that it constantly pushes boundaries and experiments with its storytelling.

The show is primarily set in an Irish bar called Paddy’s and features some of the worst people in Philadelphia constantly pursuing various self-serving schemes and getting involved in some truly unhinged antics.

One of It’s Always Sunny’s most famous episodes is The Nightman Cometh, which sees Charlie Kelly (Charlie Day) compose a whole rock opera performed by the gang.
