I eat a habanero every morning with breakfast and I use a lot of habanero sauce on my food. So, I like to think I've got a great tolerance for heat.
Yesterday I tried the Death Wings from Grinders in Kansas City. The place was on Diners Drive-Ins and Dives. I noticed the legal disclaimer on the wings and thought I'd give them a whirl. After the first taste, my eyes watered and lips burned. My stomach immediately hurt. After 6 wings I was on fire. I proceeded to consume one of their Gino's replica Phillys to calm the heat.
Turns out that their custom sauce is about 400,000 scoville units and I just ate 6 wings coated in it.
I had an abdominal tumor about 10 years ago and they had to cut through a handfull of layers of intestine to remove it. As the wings pass through, when they hit a scar area, I have intense pain, sweat profusely and get the dry heaves. It's been 18 hours and there must have been 6 places in the intestine that have been passed through. I'm at work and waiting to see if there are any additional surprises till the wings pass completly.
The wings had great flavor, but I'm not plumbed for that kind of heat anymore. If you are ever in the area, I recommend trying a toothpick dipped in the sauce to see how hot it really is.
