Well, I'm not a parent (I'm a 16 year old girl), but yes I was surprised at some of the content in this episode. One of the things I like best about this show is that it isn't sexed up and dirty, but instead is a family show. But some things in this episode were inappropraite (including Jordan coughing "asskisser" and a few other things I can't remember now lol).
But here's my advice (I know you probably don't want advice from silly little 16 year old, but whatever), don't write the show off just like that. I'm sure you know that different writers write different episodes. So maybe this episode was an experiment and the show could very well have a less dirty episode next week as a result of it coming from a different writer. So maybe just you should watch the show now without your child and see if the explicitness lessens in the next few weeks. Don't judge from just one episode, at least give it one more chance :)
