Aaah yes, The Chilli Challenge,
I remember, it would be hard to forget, taking this a few years ago, and can confirm it is ermm, challenging. And I speak as someone who pretty well likes chilli with everything, and will always go for the hot option. I've just finished a bottle of something called Crazy Daves Crazy Chilli Sauce from Loiusiana, and it was no picnic, but Rustys tincture knocks it into a cocked hat.
Make sure you have a camera when you take your "friend" along for the challenge, just to remind them later what they looked like, incase they start boasting.
