Danish YouTuber and self-proclaimed hot pepper enthusiast, Klaus Pilgaard, better known as Chili Klaus, has a hilarious way of spicing up your holiday season. He challenged Denmark’s Herning Boys Choir to eat a bunch of chilis while singing Christmas carols. The result is one of the most tortured renditions of “O Come All Ye Faithful” that you will ever witness.

The clip below is especially deranged. Things start out precious enough, as the pepper-less choir belt an amazing verse of the holiday classic. But then, just slightly over a minute into their performance, they’re instructed to eat the devilish peppers. Watch out ’cause Chili Klaus is coming to town!

In an interview with Buzzfeed, Pilgaard discussed the method to his madness. “I graduated the chili peppers a bit. The mildest for the youngest boys and the hottest for the grown ups— to make a common experience for all of them,” he said. The peppers consumed in the video range from ghost peppers to the milder (but still very spicy) Chocolate Bhutlah and cayenne peppers.

As mentioned, some of the older participants did endure ghost chiles, which are one of the hottest peppers in the world. They measure in at a million Scoville heat units. That’s over 100d times hotter than a standard jalapeño. In other words, it’s a lot of heat, especially for anyone trying to sing their hearts out.

These boys really try though. Through the tears and the coughs and the burning sting, some still manage to sing as if they haven’t been hit with a whopping avalanche of peppery pain. Despite the anguish, it’s still a nearly flawless performance. Seriously, you try staying on pitch under more sobering circumstances. If you’re anything like me, you can’t. So kudos boys! Here’s hoping you get everything you want for Christmas. You earned it.
