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.

Specifically, that It’s Always Sunny In Philadelphia and Mythic Quest co-creator Rob McElhenney had filed paperwork to legally change his name to “Rob Mac,” acting on a re-branding he’d floated a few weeks earlier in a Variety profile of himself and wife Kaitlin Olson.

Rob McElhenney has filed legal documents to change his name. The actor reportedly signed the docs Thursday requesting that his surname be changed to Mac — so his new name will be Rob Mac, according to multiple outlets.
