A few weeks ago pics of very, very chubby Rob McElhenney surfaced. The "It's Always Sunny In Philadelphia" star apparently put on about 50-pounds for the upcoming upcoming seventh season. Back in June, Charlie Day told Screen Junkies, "It’s been disgusting to watch him go through with this adventure. We were a little on the fence about it for his own personal health and safety, but it has definitely made Mac a lot funnier.” Over the weekend a new, "Fat Mac" teaser for "It's Always Sunny" hit the web. Though it'd probably be best for McElhenney to lose all that weight, we're far more excited than we should be for the story arch about Mac's inevitable heart attack.
