It might seem like we’re clowning around with this pick, but marketing to kids is as frightening as clowns themselves. A 2008 report by the Federal Trade Commission found that in 2006, Big Food spent $1.6 billion hawking their sweetly fattening wares to children and teenagers. Soda companies spent the most, closely followed by fast-food chains and breakfast cereal companies. So why Ronnie instead of Coca-Cola? Say it with us: Clowns are just creepy.
