The moral of the story is this: Do not eat a Dorset Naga. Especially when it's bright red and emits a low humming sound.
Incidentally, after the events shown in the vid I found myself experiencing severe nausea and stomach pain, so wound up back in the toilets chucking up my guts to get rid of the remnants of the chilli that I must've swallowed. I never thought that a chilli could deliver such a powerful kick, but I've been proven wrong in spectacular fashion.
FAIL.
