COPIAGUE - For the nay-sayers who claim St. Nick isn't real, here's some proof: Santa Claus is a father of four who lives in Suffolk County, and he has the driver's license to prove it.

The Copiague resident formerly known as Frank Pascuzzi legally changed his name to Santa Claus back in February. He says when he made the change, the court system did some research to make sure he didn't have suspicious intentions, but when it was approved, the judge gave him a big hug and said, "Merry Christmas, you're now known as Santa Claus."

There are at least 15 people in the U.S. with the name Santa Claus, but there's only one in New York state. Most kids who meet Claus at White Post Farms in Melville around the holidays have no idea they're meeting an authentic Santa.

Taking toy orders isn't his Claus' only job. He also designs fire sprinklers and has a barbecue catering business.
