The portrait also gives fans a good look at costar Rob McElhenney's 50 lb. weight gain
, which the actor underwent to expand his character Mac's comedic story lines. "It's been disgusting to watch him go through with this adventure," Day said. "But it has definitely made Mac a lot funnier."

Glenn Howerton, Danny DeVito and McElhenney's real-life wife
