A while back, we had a story about a Wisconsin teen who threw a kegger for friends who got kicked off school sports because they'd allegedly been caught drinking. Only his keg was full of root beer. The police showed up and gave everybody Breathalyzer tests regardless.
Here's the video, but be warned -- LOTS OF FOUL LANGUAGE. And from a technical standpoint, their audio editing needs a great deal of work.
