Once, when I was at band camp.....
I was leaning over to get a little snort out of the vial cap when I kind of hicupped and then blew it out of the cap and the end result was a liberal dusting of the eyeball - after the intial burn (painful-can't begin to describe), one side of my face got kind of numb then really numb and I looked and sounded like Slyvester Stalone. But I wouldn't recomend this method - high sacrifice and low reward - meow
