Throughout the course of its unprecedented 12 season run, It’s Always Sunny in Philadelphia has become beloved worldwide for its trademark black humour and the increasingly depraved behaviour of its morally bankrupt characters.
Revolving around a gang of narcissistic degenerates that try (and usually fail) to run Paddy’s Irish Pub, Philadelphia’s worst bar, It’s Always Sunny has never been reluctant to find the humour in some of the darkest topics imaginable. We've had Nazis, terrorism and incest to name but a few.
This black humour however, whilst incredibly funny for fans of the show, has been known to court controversy from time to time, with some arguing that in places the show has gone too far.
Although this is a valid criticism, many would argue that one of the main points of the show is that, especially for the most controversial topics, the fact a gang of absolute degenerates are horrified by the actions of their fellow characters only goes to emphasise how offensive these actions are.
So with It’s Always Sunny’s long-awaited 13th season nearly upon us. It's a good time to take a look back at their most controversial moments so far.
