John Mayer dropped by YouTube’s First We Feast channel to join host Sean Evans for the season finale of Hot Ones. If you’re unfamiliar, Hot Ones is a fascinating show with a fairly simple premise: Evans interviews celebrities while they eat chicken wings covered in a variety of hot sauces. The kicker is that only some of these hot sauces could be described as garden variety. You see, while the banter stays cordial throughout the interview, the sauces get progressively spicier.

How spicy do the sauces get, you ask? Well, your average Tabasco sauce clocks in at roughly 2,000 Scovilles (science’s preferred unit of spice measurement). But the final Hot Ones sauce that Evans forces his guests to consume? That stuff is 2,000,000 Scovilles—literally a thousand times stronger.

Anyway, Mayer’s descent in the into the deepest depths of hot wing hell is pretty darn entertaining. Partially because of the spice factor, but mostly because of the conversation. Over the course of 20 minutes, the pair dives into topics like Dave Chapelle, Justin Bieber, life in Montana, and, of course, rock’s greatest guitar faces. Finally, the whole thing reaches its climax with little ukulele jam before Mayer wraps things up with a request for people who wear Grateful Dead shirts but don’t know any of the band’s songs. You can check it all out below.
