We've seen people go to extreme lengths for both charity and eBay auctions, but this particular item, a copy of Grand Theft Auto III signed by fan fave Jack Thompson at VGXPO, combines the two in an attractive package. According to the listing, the PlayStation 2 version of the game can be yours (we think) for the low, low price of $US 4,000, the proceeds of which will be redirected in full to the Child's Play charity. There's even a picture of the signee and auction lister—who we're told is not TV's famous Wil Wheaton—to aid in the proof of authenticity.
What is suspect, however, is whether you actually get the signed copy of the game for your four large, seemingly the entire point of dropping this much cash on a used PS2 game. The eBay listing comes with the unclear note "Please note: I do not actually want to sell this. I am just listing it for show and to hopefully win a contest. However, if you want to spend $US 4000 on this then I will donate 100% of the proceeds to Child's Play Charity." The seller does have a 99.9% positive rating, so I wager you'll be satisfied. If you do decide to give up the cash, let us know when (and if) you get it.
