This is a video from the 2010 PAX East convention in which two dudes instruct a crowd full of people to crack their knuckles on the count of three. Anyone else cringe and then, immediately, instinctively crack their own knuckles? While a room full of people cracking their knuckles is pretty gnar gnar, call me when they get em all to scrape forks between their teeth. You know, as a warning. I don’t wanna be around for any of that mess!
