I got the rules here:

1. Sign the waiver admitting that your ignorant of personal danger, swollen lips, dry tear ducts, explosive bodily functions and overall unpleasantness after touching your eyes or various body parts.
2.Participant has 7 minutes to eat seven 7-alarm wings to the bone (yeah, that means no meat left... only bones)
3. You cannot eat or drink ANYTHING during the 7 minutes
4. No napkins are allowed during the challenge
5. Participant must lick clean any sauce on hands before the 7 minutes are up!
It's crazy, I'm not sure what hot sauce they use, but I've heard stories from friends about their experiences doing the challenge.
