This is a fake 800 number from a parody video of the Girls Gone Wild commercials.
The joke video is called "Girls Gone Wild - Fat Girls Gone Wild".

And, yes... Like supere52 already said.. 800-328-4475 spells out 800-FAT-GIRL.

The 2 idiots who called from this number claimed to be from specialty graphics. They used words like GD and yelled at the receptionist stating they would be getting drunk and come down and take care of her.

800-Fat-Girl.... where is is easy to stick it in, your credit card that is!
