Editing It's Always Sunny in Philadelphia

'''''It's Always Sunny in Philadelphia''''' (also known as '''''It's Always Sunny''''', '''''Always Sunny''''' or just '''''Sunny''''') is an American television sitcom which premiered on FX on August 4, 2005. The series was created and developed by Rob McElhenney, Glenn Howerton, and Charlie Day, who also star in the show. The series follows the exploits of "The Gang", a group of self-centered friends who run Paddy's Pub, a relatively unsuccessful Irish bar in South Philadelphia.

The show aired on FX for eight seasons before moving to FXX. It became the longest running live-action comedy series on basic cable as of Season 9.

On December 10, 2020, it was announced that the show had been renewed for an additional 4 seasons, which would take it through its 18th season, making it the longest running live action comedy program of all time. The show most recently completed its 17th season.

In the intro of the show, actors appear in the order of their birthdays:

* Charlie Day - February 9, 1976
* Glenn Howerton - April 13, 1976
* Rob McElhenney - April 14, 1977
* Kaitlin Olson - August 18, 1975
* Danny DeVito - November 17, 1944

Glenn Howerton is omitted from the opening title sequence in the first episode of Season 13, "The Gang Makes Paddy's Great Again", but the closing credits have a "Starring Glenn Howerton" credit.  This was due to the fact that Season 12 ended on a cliffhanger in which Dennis left for North Dakota, and Glenn Howerton himself had said he may not return to the show, due to his workload on his show "AP Bio."  He returns to his normal position in the opening credits with the second episode of Season 13, "The Gang Escapes."  He's listed in the opening credits of the third episode of Season 13, "The Gang Beats Boggs: Ladies Reboot", despite not being in the episode.
