I missed this when it hit the news two weeks ago, but some 7500 gamers unwittingly sold their souls to GameStation earlier this month. In an April Fool's joke, but one with a serious point to make, they inserted the following clause into their online contract;
"By placing an order via this Web site on the first day of the fourth month of the year 2010 Anno Domini, you agree to grant Us a non transferable option to claim, for now and for ever more, your immortal soul. Should We wish to exercise this option, you agree to surrender your immortal soul, and any claim you may have on it, within 5 (five) working days of receiving written notification from gamesation.co.uk or one of its duly authorised minions."
The point, of course, is how many of us click through contracts without really reading them. Bad on us. The roughly 10% who did read it, and selected the opt-out option provided, were rewarded with a £5 voucher and the right to entertain other options on their souls. Perhaps the most amusing part - or, perhaps not - is that the company feels compelled to email all these people and explicitly waive all claims to any souls, just because there are a lot of yahoos who would seriously worry about a thing like that.
