Fat Mac from It’s Always Sunny in Philadelphia

Ronald “Mac” McDonald is a main character of It’s Always Sunny In Philadelphia. In season 7, Mac gains a significant amount of weight, earning him the nickname “Fat Mac.” However, everyone but Mac seems to recognize this. He tries to explain that he’s “cultivating mass,” mistaking his fat for muscle. While this costume guide contains a belly stuffer, Rob McElhenney, who plays the aforementioned character, actually gained sixty pounds for a realistic effect.

Mac as Nightman

Mac plays by his own rules and proved such when he cast himself as the leading role in Charlie’s play, Nightman Cometh. The character was a perfect excuse for him to show off his muscles and cat like reflexes. The hissing sounds were just an added bonus.
