Rob McElhenney isn’t making any apologies over his decision to change his name, but he is making a few jokes about it. The “It’s Always Sunny in Philadelphia” star addressed the move amid reports he has filed paperwork to change his name.

Rob McElhenney has seen the online discourse around his name change and is chiming in. The Emmy winner, who made headlines for filing to legally change his name to Rob Mac last week, took to social media to “dedicate exactly one minute” to explaining why he took such significant measures.

Rob McElhenney’s new last name has high potential. But for his wife and “It’s Always Sunny in Philadelphia” co-star, Kaitlin Olson, she isn’t fazed by the switch-up from McElhenney to “Mac.” The actor filed to legally change his name last week and is waiting for the court to make it official.
