Chris Kempczinski, the chief executive of McDonald's, faced widespread teasing online after a promotional video in which he reviewed the company’s newly launched Big Arch burger went viral across social media platforms.

The fast-food chain introduced the Big Arch burger this week as a limited-time menu item. According to McDonald’s, the sandwich features two quarter-pound beef patties, three slices of cheddar cheese, lettuce, pickles, crispy and slivered onions, and a signature sauce served on a toasted sesame and poppy seed bun.

Kempczinski posted a video review of the burger to Instagram, where it quickly attracted millions of views. In the clip, the CEO expresses surprise at the size of the sandwich before taking a small bite and offering praise for the new item.

“Holy cow! God, that is a big burger,” Kempczinski said in the video before tasting it. He later described the sandwich as a “delicious product” that he said was “distinctively McDonald’s.”

The short clip generated more than 4.5 million views and sparked a wave of reactions in the comment section, where many users poked fun at the executive’s presentation.

Several commenters joked about what they described as the notably small first bite Kempczinski took during the demonstration. Others teased his reaction to the burger’s appearance, with one user writing that the CEO seemed impressed simply by the sesame seeds on the bun.

Several users also focused on Kempczinski’s use of the word “product” to describe the burger. Some commenters said the corporate phrasing sounded unusual when referring to food, with one joking that it made the sandwich sound like a retail item rather than a meal.

Despite the online ribbing, the video succeeded in drawing attention to the company’s latest promotional rollout. McDonald’s described the Big Arch burger as featuring a tangy and creamy signature sauce designed to balance mustard, pickle and sweet tomato flavors.

The launch is part of the company’s broader strategy to keep customers engaged with new and limited-time menu items. Earlier this year, the chain also drew headlines with a promotional giveaway featuring specialty McNugget “caviar” kits that included premium sturgeon caviar and crème fraîche. The kits quickly sold out, with some customers reporting website disruptions due to high demand.

Company representatives said at the time that the promotion was part of an effort to create unique experiences around the brand’s menu offerings and attract interest from longtime fans as well as new customers.
