I have a bottle of that in my frig now. I also gave my dad a bottle of it a few years ago. He got confused one day as to how hot it was and dumped a bunch in his food and just lit himself on fire. He had diarrhea for 2 days and forgot the day before he ate some of it and that it burns on both ends.

There are a few things hotter than Dave's insanity sauce but not much. There's the Source which is just pure heat, like 7 million Scoville units.
