Your dog could be a rat

You may want to dump those sketchy Gilmore Girls DVDs you bought three for a quarter last summer at the flea market -- especially if you see a snarling black Labrador racing for your door. Broadcasting & Cable reports today that the Motion Picture Association of America has trained two dogs to sniff out the polycarbonate used in making counterfeit DVDs. They've already detected a load of pirate discs in a Fed Ex shipment at Great Britain's Stansted airport. Now they're on a grand tour of Washington, Los Angeles, Singapore, Hong Kong, Dubai and the United Kingdom. The dogs -- named Lucky and Flo -- were trained in Northern Island, so if you're cornered, trying bribing them with corned beef and cabbage, or possibly a Guinness.
