When my neice and nephew stay with us, we get quite a bit of HannahMontanna & iCarly. My son's behavior, actions, and speech patterns change a GREAT deal after just a week or two of these shows. :P
Ya wanna uncock your shoulders and your eyebrow and try that again, mister?
The idea that kids/teens need to be "at odds" with their parents and other authority figures is one of the most pervasive themes in a lot of 'new' shows (past 20/30 years).
And YET, when we go on a binge of watching FAR more adult programming, and older TV where the "attitude" and "at odds" aspect is replaced with 'trusted mentor'... low and behold after just a few weeks THOSE behaviors, actions, and speech patterns start to replicate themselves in my son.
Kids really are sponges, both statistically and anecdotally. I've learned, if I don't want my son acting *exactly* like what he's watching on TV (or around certain groups of people) the way to circumvent that is to NOT have him watch those types of TV or be around those groups of people.
So personally, I'd strongly recommend against it.
The heart of a child is a precious thing.
