Chilli sauce from hell
A few years ago I was give a bottle of Dave's Insanity Sauce. For those of you who've never had it: it's hot. I like spicy food but one drop of this in a bowl of soup renders it almost inedible, it's ridiculous.

So, one day at work, my colleague Mo mentioned spicy food (Mo's already starred in a previous qotw answer).

I mentioned the Insanity Sauce, Mo sugested it probably wasn't as hot as I was making out, so I dared him to eat some on a rice cracker the next day, when I brought it in to work.

So the following day, I wandered over to Mo's desk, presented him with the sauce, whereupon he assumed I was playing a nasty trick on him and it would be horrible. To prove it was edible I had a tiny drop on a cracker first, which was decidedly unpleasant.

Seeing this, Mo did the same, and exclaimed "Oh, it's not that hot, it's no worse than a vindaloo!".

He then proceeded to liberally douse another cracker with mucho sauce, and eat it. I was (secretly) gutted that he wasn't impressed, congratulated him and sat back down.

A couple of minutes passed, and then another colleague, Amy, who hadn't seen the cracker episode came into the office and asked "Why is Mo out crying by the water cooler?"

That stuff is pure fucking EVIL
A bloke called Dave once proudly turned up with a bottle of that at a party. He spent the night trying to convince people to take sips of it, I fell for it and it was agony, although I was better off than Jim, who downed a fucking shot. He was NOT a happy bunny after that!

Eye
At a party tried some of this on some food (I forget which) and it was, as said, very hot.

What I didn't realise is I got some on my fingers and scratched my eye 10 minutes later, the feeling of burning made me feel like I would never be able to see out of that eye again.

3 Hours later (and lots of splashing of water) I was ok again.

If you like fuck-off hot sauces.
Daves' Insanity is warm at 180,000 scoville units *
I have a bottle of Blair's Mega Death Sauce at 550,000 units, it's a tad warmer. Even a tip of a toothpick amount on the tongue is fiery hell. I use it in chilli con carne though and it's bloody great.

* Scovilles are the "arggh" factor unit of measurement, pepper spray tips the scales at about 2 million units.

I dare someone
To rub that stuff on their genitals.
I've done it without meaning to (on hands, go take a piss) and it's the most painful experience of my life.
However...
After about an hour it felt really good, endorphins etc. Try it!
