How did a sitcom about five thoroughly awful people become such a comfort watch? We explore the enduring appeal of It’s Always Sunny in Philadelphia, from its live-action cartoon characters to the cleverness that eventually won Amanda over, despite the gross-out moments. We also revisit “The Nightman Cometh”, Charlie’s rock opera masterpiece, with trivia, chaotic gang dynamics and the contribution of a live audience. Plus, we discuss Kaitlin Olsen’s influence on the show. Dayman would approve. Probably.
