Please do not eat ghost peppers before a choir performance

Ever wondered what it would be like to sing "O Come, All Ye Faithful" after downing a ghost pepper? Probably not, but you should probably watch this video now that your curiosity's piqued. 

Chili Klaus, a YouTuber already famous for the clip of orchestra members eating ghost peppers, has now pivoted his experiment to Denmark's Herning Boys Choir. The group sounds perfectly delightful during their pepper-free run of the song, but once the heat hits, many of the choristers have a hard time keeping up with their parts. 

This is to be expected, of course — once over a million Scoville units are in your mouth, it can be difficult to concentrate on anything else. Still, there are a few singers who just chug on through the pepper pain like it's nothing. We assume these musicians either eat ghost peppers for breakfast or are robots.
