McDonald's CEO Chris Kempczinski named the villain behind his infamous viral February video testing out a new burger. "I blame it all on my mom, because she told me, 'Don't talk with your mouth full,'" he said in an interview about the Instagram reel with The Wall Street Journal, released on Monday. "And I think probably in that case I should have just said, 'You know what? To hell with it. I'm gonna talk with my mouth full,'" he added. In the reel he posted on February 4, Kempczinski taste-tested McDonald's new Big Arch burger, to the internet's dismay. Social media users zeroed in on his robotic body language, noting how small a bite he took, and how he repeatedly called the burger a "product."
