I have to get one of those. I've taken a bite of a Bhut Jolokia, a Scorpion Butch T, and a Scorpion Moruga and cooked with all 3. Peppers have pretty much reached the point where the numbers and the bragging rights are about the only differences between them in terms of heat. They are so hot now that it is almost impossible to notice any increase in heat from one scorching hot pepper to the next.
I agree with the "thrill seekers" analogy, though. I'll sacrifice flavor in pursuit of heat from time to time just for the thrill. If a restaurant has a spicy challenge, I'm all for it. Haven't found anything that is too hot to eat......yet.
