For those who aren’t familiar with the Heart Attack Grill, it’s a restaurant that aims to be as unhealthy as possible. Their showboat item is called an Octuple Bypass Burger, which has eight patties stacked with lettuce, tomato, sauce, cheese and, of course, butter — with 40 slices of bacon optional. Plus, if you’re over 350 pounds, you eat for free!

It’s a simple, eye-catching enough premise, if a bit a little too on-the-nose American. But mosey on over to their YouTube channel and you’ll find something weird.

Basically, it’s filled with videos of their servers, wearing nurse costumes, doing very uncommitted lip syncs to popular songs. Often, these sing-alongs happen in front of imagery from the restaurant. Sometimes, there’s no lip-syncing at all, with the restaurant opting instead to use green screens to place their servers’ offbeat moves in front of images of burgers and milkshakes.

You might be thinking that this is some promotional effort. If it is, they certainly need to do a better job getting the word out. Most of these videos have around a hundred views tops, and even the ones that have more than that are lacking any contextual information.

If you just stumbled upon one of these, you’d probably think you were having a medical episode — perhaps, a heart attack.

Wait, maybe that’s the point?
