I used to have one of those for half a night or so in Wacken a few years back and then I woke up and gone was my dignity, my clothes, my drinking horn, my hopes for a bright future, my sanity and my cleanliness... and all I got in return was one of the worst hangovers ever which caused me to lie dying in the sun until Immortal started playing so I puked four times in different colours (black, greev, yellow and clear) and some nice lady came and was all OMG HOW R U and shit and I was like löl take a wild guess
