This must have been the inspiration for the Simpsons bit where the police set up a sting by offering a free boat giveaway

I recall an old episode of "COPS" from years ago where they showed an ongoing sting they had where they called people with warrants and told them they'd won a big screen TV and to come down to the warehouse to get it.
