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.
