Singer John Park's rap McDonald's order goes viral — now it's an actual ad

A video of singer John Park rapping an order at a McDonald's store has surpassed 3.4 million views on YouTube, generating sustained buzz online. McDonald's Korea has since turned the viral moment into an official social media ad, keeping the excitement going.

McDonald's Korea unveiled the ad on its official social media accounts Wednesday, captioned "Your order — the ad — is ready," showing Park rapping an order for a new menu item.

The ad opens by highlighting comments left on Park's YouTube channel, "John or Park," before using Park's rap to introduce the "John Park Set" — a combination of the new Big Arch burger, Coca-Cola and an Oreo McFlurry.

Within a day of posting, the ad had collected nearly 40,000 likes. Viewers responded enthusiastically, with comments including "I like John Park's song better than the original jingle," "I went and ate a Big Arch after watching this," "Please put this on TV" and "This is the most impactful McDonald's song in history."

In fact, the video of Park rapping the order was content produced through a collaboration between McDonald's Korea and Park's YouTube channel to coincide with the launch of the new Big Arch.

In the video posted to "John or Park" on Friday, Park joined fellow singer Kwak Jin-eon for a hip-hop lesson with rapper Loco before heading to a McDonald's store in Songpa-gu, Seoul, to deliver a rap order. As of Thursday, the video had racked up 3.4 million views.

One viewer had suggested in a comment — which itself received about 15,000 likes — "If I were a McDonald's executive, I'd run it as a jingle ad and launch a 'John Flavor Set' with the Big Arch and an Oreo McFlurry." That idea became reality when McDonald's Korea turned it into an official social media ad.

Meanwhile, the Big Arch featured in the ad is a new menu item McDonald's launched Monday. The oversized burger is built on a 4.5-inch chia-seed sesame bun and stacked with a double beef patty, three slices of white cheddar cheese, crispy onions and a proprietary Big Arch sauce.
