Rob McElhenney has officially shortened his name, despite mixed reactions from fans. The actor and comedian recently announced that he would now be known professionally as Rob Mac, citing years of people mispronouncing his surname. In a video posted to X, the It’s Always Sunny in Philadelphia creator addressed the shift.

Call him an actor, writer, producer, director, Welsh soccer-team owner and creator of "It's Always Sunny in Philadelphia" – just don't call him Rob McElhenney. It's Rob Mac now.
