This Saturday afternoon, open auditions for two reality shows that actually still hold my attention for more than three minutes will be held in the city. If you and a family member, coworker or friend are looking to lose weight, The Biggest Loser will be holding auditions at the NBC building (although if you can't make it, you can send in a tape by 9/4). If you are attractive and prone to rage, tears, or both, America's Next Top Model will be at the Crowne Plaza looking for their next contestants. Who Wants to Be a Millionaire will also be looking for fresh meat at Medieval Times this Friday.
