Posted in another thread, but all relevant in terms of learning how to handle seriously hot chillies the right way. Mostly Scotch Bonnets!
Being a complete chilli addict, I've had it all. Rubbed my eyes, taken a wizz, scratched my nuts, picked my nose; the works.
A few of the worst were:
Eating "fire sticks" at a festival -- basically really big Pepperami-type sticks coated with a Naga Jolokia spray. Didn't even think about it being on my hands, and did a full on two-hander face rub in the car on the way back. My whole face felt like it was on fire. The baby wipes that I had to hand only made it worse.
After chopping a bunch of Scotch Bonnets, I had to wipe my eye so used what I thought was a clear part of my arm to do so. Turns out it wasn't clear, and the ensuing pain was indescribable. It actually felt like there was a small chunk of one of the chillies trapped in my eyelid, but the wife couldn't see anything. I tried braving it out, but after 15 minutes of being completely unable to open my eye, the wife decided to give me an eyebath in the sink. Due to the angle it had to be done at, I spent the next 5 minutes essentially being waterboarded by my wife in the kitchen. Worked, though!
The singular worst was, again, after dealing with some Scotch Bonnets and Habaneros... a few hours after dinner I went for a shower -- delved into the butt crack to give the ol' hoop a quick soapy clean.
It was so painful I thought I'd opened an anal fissure or something until I cottoned on! Had to squirm, naked, on my leather computer chair for another 30 minutes or so before the pain died down.
