Danish musician and self-proclaimed "chilienthusiast" Chili Klaus is known for challenging people to eat some of the hottest chilis in the world on his .

In one of his latest challenges, he teams up with Denmark's Herning Boys Choir to spice up a classic Christmas song...literally. In the video, they sang their rendition of "Oh Come, All Ye Faithful," which started out quite beautifully. Then things changed when they all ate entire ghost peppers.

Watch as the poor boys try to keep their composure while suffering the effects of one of the hottest chili peppers you can eat. Their panicked faces say it all.

 

That they were able to keep singing at all is pretty impressive in my book. There's no way I'd try a ghost pepper at my age, let alone as a kid.
