The story of how Mac on It’s Always Sunny In Philadelphia got fat was one of the big pre-season “buzzes” before this season began. And now it looks like Mac is going to get the chance to tell his side of the story, albeit to a priest for some reason. In a totally surprising development, he blames the other members of the gang for his condition. Classic fat Mac. If you want more of the skinny on this situation for yourself, check out the next episode of the show, which airs Thursday, November 17, 2011 at 10:00 PM ET/PT on FX.
