Ah, the Red Ring of Death. Most cursed malady of this console generation, maligned by the casual and the hardcore alike! But for all the frustration the Xbox 360's three lights of crimson chaos have caused, here's a little good: If it weren't for a certain RRoD in Florida, one Michael Dunbar would never have been brought to justice. Dunbar was accused of stealing the console and pawning it off to a shop, but without the serial number, police told the victim that they couldn't bring him in. Fortunately, the victim's grandmother suddenly remembered she'd sent the system in for an RRoD, and a phone call to Microsoft later, they got a serial number, Dunbar was arrested by the police, and we assume the console was returned to its rightful owner.
Little consolation, we're sure, for the eight painful weeks you had to wait while your Xbox was sent back to Microsoft for repairs (two separate breakdowns for me personally). But it's good to hear that someone somewhere has been helped by Microsoft's RRoD exchange process.
