Fat Mac: proof that winners never quit.

[@josemaria8177]

They missed a perfect opportunity to call him "Big Mac"

[@levilepsylonake5751]

I think that's the joke

They said that “Big” implies there’s some kind of muscle, but they did say they could call him Big Fat Mac as an alternative

Mac's not fat, man. He has cultivated enough mass to a new form of physical excellence.

[@matthewriley7826]

Lol I love how “Mac getting fat” was just a big misunderstanding on his part and the gang find it hilarious😂

[@WebberLowe]

I really love that Dennis's first instinct is to laugh when Mac has diabetes but realizes he shouldn't be laughing at that and acts concerned. Glen is so good.

[@lucillelovesnegan2144]

I think he laughed because mac said he was healthier than he was and did it as a right back at you kinda thing

[@joecab1]

We tip our hats to Rob McElhenney's commitment to gaining weight because he thought it would be funny

[@FXNetworks]

He's nothing if not dedicated to his craft

The class reunion episode was the best part

[@LanaK.fan8337]

He's just big boned.

Fat Mac was great, but I feel like it over shadows alot of other great episodes and seasons…I personally think season 5 is the best season overall🤷
