20 Mind-Blowing Facts About It's Always Sunny In Philadelphia

17. Frank's Pretty Woman Is Sunny's Most Viewed Episode

Sunny's ratings have fluctuated over the years as the show initially struggled to find an audience. FX was nowhere near the channel it is today in 2005 when Sunny debuted on the network. The ratings only really stabilised when Sunny built up enough of a cult following and FX starting to promote the show more heavily. The highest rating for an episode of the show is 2.28 million viewers for the season seven premier Frank's Pretty Woman. It was a good episode and kicked off a very strong season of the show in style. Of course, way more than 2.28 million people will have watched that and other episodes through other means (downloading, TiVo etc.). Sunny has never been a huge ratings success like other shows but it definitely has a loyal and dedicated fan base, which was proven when a substantial amount of them followed Sunny to new sister channel FXX in 2013.
