Good lord. Why would you ask such a thing? I could not possibly. Season 7 is my favourite season and even that was a struggle to pick.

My favourite of the most recent series was The Gang Tries Desperately to Win an Award, not only because it is a wonderful send up of everything wrong with sitcoms and addresses the smurfing offensive injustice of It's Always Sunny never getting nominated, but also because of Charlie's beautiful song at the end. https://m.youtube.com/watch?v=y-lolbx6-5s
