In June 2011, it was reported that Rob McElhenney had gained fifty pounds in the previous six months. McElhenney has stated that he noticed characters from other sitcoms get better looking as the series progress (because the budgets get bigger, and that means more and better make-up people), but McElhenny wanted his character to do the opposite. Co-star Glenn Howerton started referring to the character Mac as "Fat Mac". When McElhenney asked if he could be called "Big Mac", Howerton said he would call him "Big, fat Mac".

Every installment of the Gang's "Lethal Weapon" sequels involves Dennis playing Martin Riggs (with a thick Australian accent, satirizing Mel Gibson's inability to maintain a consistent American accent during the early "Lethal" movies), and Mac as Roger Murtaugh (in full, and completely offensive, blackface). The two always switch characters halfway through. Both actors perform spot-on imitations of Danny Glover's voice.

All of this would make him a good candidate for Antisocial Personality Disorder (a sociopath), wherein he experiences an inability to socialize properly, and often resorts to substance abuse (further evidenced by his alcoholism and his addiction to crack).
