"The Americans are more action-oriented. They want to see the puppets beating each other up. British audiences are more intellectual. They like to see it sick and twisted but in an intellectual way."

I like intellectually sick and twisted action! Actually, I just like the idea of muppets behaving badly. There's something as wrong and amusing about it, as there is about all the dirty cartoons with the Jetsons that I find when I peruse "certain sites" if you catch my drift. Nothing says "adult entertainment" like your childhood buddies going wrong...
