The current season of It’s Always Sunny In Philadelphia on FX is drawing to a close, with the conclusion of the gang’s trip to their high school reunion. Unfortunately, it looks like they’re having as much difficulty fitting in as they had when they were actually in high school. Don’t feel too bad for them, though – the name of the episode is “The Gang’s Revenge,” so we might be looking at some Carrie-esque violence here. Or maybe just a musical number. If you want to find out which it’ll be for sure, the finale airs Thursday, December 15, 2011 at 10:00 PM ET/PT on FX.
