"You remind me of that scene from Zoolander....the one where the male models are dancing while spraying each other with gasoline..."
"If there is anything that this horrible tragedy can teach us, it's that a male model's life is a precious, precious commodity. Just because we have chiseled abs and stunning features, it doesn't mean that we too can't not die in a freak gasoline fight accident. " ~Derek Zoolander
