Here's what you do for INSTANT fame (your definite 15 mintes):
Wait until somebody really powerful and famous comes to town, or go to where yo uknow they're going to be (this works really well with political or religious figures.
Wait for the right moment during their parade or speech or that "I'm a people person visit" to wherever, then drop your clothes (be sureyou have something bodypainted on) and go running through the medai's view nd shouting something cmpletely ludicrous like "The cans of Spam are trying to eat my brain!" or "Lindsey Lohan is a fine actress" or "Ryan Seacrest has captured the hearts and minds or America's youth through mind altering chemicals transmitted through my TV!"
That'll ASSUREDLY make you famous for a short while.
