Biggest Loser poor language

I know many of my friends were appalled by the language used on the premier episode of the biggest loser last week. Please let our voices be heard by going to www.nbc.com and letting them know this is un-called for.
After you get on their website, scroll to the bottom of the page where you will find a "contact us" link. From there scroll down till you come to a pull-down menu where u can choose the show, this will open a new window where u type your name and email address and your comments. Thanks for taking action. If we just complain about it , but do NOTHING about it, we will see no change.
