This is one of the most consistently funny shows I think I ever have seen and I say that after watching another hilarious season(14). I personally re watched the whole series recently over a course of a month and its even better when you have that kind of continuity since everything is connect. There are only two other shows that Ive seen(in my lifetime) that are this consistently funny; Seinfeld and Curb. But to Its Always Sunny's credit they have made way more seasons and compared to Curb in a shorter amount of time.
