I've been re-watching some seasons of It's Always Sunny and I keep coming back to season five. It has, in my opinion, the most classic episodes from any season and is consistently great from start to finish. We have The D.E.N.N.I.S System, The Gang Hits the Road, The Gang Gives Frank an Intervention, Paddy's Pub: Home of the Original Kitten Mittens, The Waitress is Getting Married, Mac and Dennis Break Up, The Gang Reignites the Rivalry. Seasons three and four are really strong as well, I'd definitely have them as my runner ups. So, Mayberry, which is your favorite?
