it's very simple. all the challenge entails is that you and your friends and an array of un/willing accomplices see how many times you can listen to the Ace of Spades, by Motorhead, on repeat.
it's a fun way to freak out all the cool kids at clubs. hell, it's a fun way to scare away all your friends. not to mention getting on the nerves of an entire student body.
here's how we did it:
-take a dj slot on college radio (mondays, 2pm).
-take a cd copy of the Ace of Spades.
-publicize your event (posters and word-of mouth will do. so will holding people's pets to ransom, but I must advise you only do this in the most extreme circumstances)
-inflict the Ace of Spades Challenge upon hundreds of 16-19 students on their lunch breaks.
sarcasticmuffin and I tried this last week, but unfortunately the Reception desk has a killswitch.
just a rough idea, because I don't have a scanner
