This is insane! Ive never seen anybody do this! http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoid=31920082
I really think you needed a disclaimer telling no one to attempt it, how many people are going to get drunk at the weekend now and think "hey I know what I can try"
Sort of reminds me of some of the tricks guy do on slack rope walking. I'm almost inclined to day it's not real. The frame rate looks awfully odd. But that could be down to someone funky telephone and that it's filmed at night. I can just see someone seeing this and then trying it themselves... cracked skull time.
