Okay, where do I begin, CS? First off, the characters putting each other down is usually meant to be in good fun. Like it or not, there are a lot of people in REAL LIFE who talk to each other like that. They don't usually get offended by it either. As for their desire to be cool, there's only one character who fits that description, and that's Carver. Everyone else is fully confident being him/herself. I'm getting the impression you watched that episode where Carver becomes accepted by the cool kids and based the ENTIRE series off of that.
Furthermore, wow, how did you guys miss the messages in this show? Not only does every episode contain a life lesson, but to make sure kids know what to pick up on, they end every episode with a character summarizing the lesson. (Most of the time, it's Tino) I mean, wow, it couldn't be more clear. Also, when is the word "crap" ever used? I've watched every episode and they NEVER say that! I love how you guys sometimes make things up just to complain.
As for the show itself, it's hilarious, watch it. I'm done.
