Rob McElhenney Explains Decision to Change Name


Rob McElhenney isnโ€™t making any apologies over his decision to change his name, but he is making a few jokes about it.

The โ€œItโ€™s Always Sunny in Philadelphiaโ€ star addressed the move amid reports he has filed paperwork to change his name.

โ€œYes, Iโ€™m shortening my name to Rob Mac,โ€ he said in the July 1 clip he posted on X, confirming the news himself. โ€œMostly a stage name, but I digress.โ€

He then used his trademark humor to explain just what has gone into his decision.

โ€œThe amount of time that I have wasted trying to get people to either say or spell my name correctly is literally days of my life,โ€ he said, as quick clips of others saying his name wrong played in the middle of him speaking, โ€œTrust me, I added it up.

โ€œMore importantly, it means thousands of you have had minutes of your life stolen by me because of my last name.โ€

McElhenney playfully pointed out the false connection the family has to the moniker.

โ€œStill, itโ€™s a family name,โ€ he said. โ€œMy grandparents, parents, siblings, aunts, uncles, cousins and I all share it, and I love them and I want to stay connected. Thereโ€™s heritage. Except, itโ€™s not even really our f—— name.

He then explained how different generations have changed the spelling of it.

โ€œThe current one was just given to my ancestor by a government official who decided that this was now the spelling,โ€ he said, while also revealing his great-great-grandmother went by Bridget McIllhenny.

McElhenney then dove into how ridiculous the whole matter is.

โ€œTimes have changed and most people already call me Rob Mac anyway,โ€ he said. โ€œMy family knows me and loves me regardless of how many syllables I have, and thatโ€™s the only thing that I really care about. There are so many things going on in the world, and this is a silly one to continue to waste your time with.”

McElhenney also said heโ€™s OK with whatever name people want to give him, using the actual first names of celebrities as their pictures appeared on the screen.

โ€œHonestly, call me whatever you want: Marion, Jerome, Archibald, Eric, Maurice, Stephanie, Frances, Marvin, Gordon or Sam. But maybe we just keep it simple and try Rob Mac. Letโ€™s see how it goes,โ€ he said.

In May, McElhenney opened up about how he was mulling over a name change in the wake of his multimedia company, More Better Industries, adding to its global portfolio.

โ€œAs our business and our storytelling is expanding into other regions of the world and other languages in which my name is even harder to pronounce, Iโ€™m just going by Rob Mac,โ€ he told Variety.

The level of difficulty in pronouncing โ€œMcElhenneyโ€ is old hat. In 2023, his friend and fellow co-owner of Wrexham A.F.C. soccer club, Ryan Reynolds, released a humorous video about how to say it.

โ€œItโ€™s Mackle-Henney, itโ€™s Mackle-Henney,โ€ Reynolds sang with a roster of guest stars, including McElhenney’s wife, Kaitlin Olson, and Philadelphia Eagles legend Jason Kelce.
