A video of the head of the iconic fast food chain trying a new menu item has gone viral, with social media and online comedians mocking his awkward taste test and citing it as evidence that he did not enjoy the experience of his own firm’s burger. In the clip, which was posted in February but went viral over the weekend, Kempczinski talks about how much he loves the new Big Arch burger, which he calls the “product” – an unusual moniker for a sandwich.
