I don't think we should look for people who are just trying to go about their lives and make fun of them and degrade them. That is just wrong. But what about clowns? They get paid good money for us to make fun of. It is part of the human condition to make fun of others doing stupid things. This is a good educational tool. Not, these kids, posing for pictures, allowing themselves to be made into media-circus-bait, how are they any different than a clown?
I don't make fun of people in real life. You willing get put on TV or in a magazine, you're open game.
