LOL. Don't believe what you see on Man Vs Food; wiki either for that matter. You might be right about the Scotch Bonnet though; never tried one but Food network listed it as the same pepper as Habaero and Thai Peppers. All that said, I suspect even the same species of chili might be hotter when grown in one plac over another.
As for there being hotter peppers that AREN"T considered edible, IIRC the ones that are considered edible are the coolest 8%-10%
The original Tabasco was/is made from Jalepenos (considered around the middle of the scale of edible although I've found wide variation from 1 Jalepeno to another) There is a Habanero Tabasco out now also.
I believe what I see (mostly) and some of what I read! I dont know your source of info, perhaps if I did I would be more inclined to take your word for it rather what Wiki or Man vs Food has to say (I dont see that my source of info is any more or less reliable than yours unless you know different?), besides if you would have seen his face, the sweat and his swollen lips, you would believe that he did what he showed himself doing.
Anyhow, like I said earlier, I have tried a Habanero chili with a Scoville rating of 100,000 350,000 and dont really want to try it again I like chilies and spray Tear gas in my mouth as a breath freshener GRRR‼‼, but my rear end and I dont like each other the next day after a hot curry!
I have a bottle of Who Dares Wins by Hot-Headz (www.hot-headz.com), which has a Caution: avoid contact with eyes and sensitive skin. And although it doesnt have a SHU on it does go to Aaaaah‼ on its scale of heat. I bought it in the UK (Tel 01453731052), phone them and buy some. (Not connection to seller)
