What's the hottest hot sauce you've tried?

Dave's Insanity, Scorpion.

We like home made things more than something we can buy. The Mrs comes from a long line of TexMex and Apachee people.... Her original Salsa is plenty hot for most people, in fact it is too hot for us today. (hell getting older) But she used to make her normal, then because some people just couldn't deal with the real thing she made a milder version. But if we were having a party she would make up a batch of what I named "I dare you". I'm not sure if there was anything in it other than Habaneros and Tomatillos. Of course her recipe went only to her daughters.... And now granddaughters.

Something my Son got me once. Don't remember much about it other than the work "Bitch" was in the name.
