It's not that viral yet, or not as far as I know, I found it on a tech blog. It should be, though. :)

I did something similar years ago when a bunch of us at work were trying out these killer nucular atomic hot wings, I dipped my finger into the sauce just enough to get one drop, then tasted it. Holy shit that was like eating hot lava. It took a while for the fire to subside. Other people looked like they had been maced after a couple bites. I thought I had wiped off any residue from my finger, but after lunch I rubbed my eye and I wanted to dig it out of my skull with a screwdriver.
