It's a cute show (I'm 13, btw) but definitely not appropriate for younger kids (e.g. eight and younger). I suppose mature kids could watch it. It's Disney, so you'd think it would be a funny family show, but there are way too many sexual jokes that irritate me whenever my 7 year old sisters watch it.
Here are some examples:
(Teddy to her parents) "Okay, have fun! But not too much fun - we have enough kids."
Mom: And then I met dad.
Teddy: And if you hadn't, then I wouldn't be here today!
[Note: this one seems okay, except my sister couldn't stop "pointing out" that Teddy would still be there - because "you only need a mom to make a baby right? right?"]
Gabe: (to Mom) Did Dad ever get nervous talking to you?
Mom: Oh, when your Dad and I started dating we didn't do a lot of talking. Mostly we just...
Gabe: Just what?
Mom: Played checkers...lots and lots of checkers.
On the 2-part special where they go on a family vacation, there are WAY too many inappropriate jokes... here's the scene:
Mom: Big news!
Teddy (15 years old): Please tell us you're not having another baby.
Mom: No, we're not having another baby. And I can assure you, we're not making that announcement ever again.
Teddy: Yeah, this family is big enough - you completely clear on that dad?
Dad: Why're you pointing your finger at me? Having babies is a team effort.
Gabe (10 yrs old): What do you mean?
Teddy: This should be good.
Dad: Uh, you know what? Getting back to that announcement, we're going on a family vacation!......The place is called Mountain Bliss and it's
Mom: Where your dad and I got married.
Dad: You know the weekend we got married, we weren't even planning on doing it!
Mom: Getting married....Then we met judge lawson and he said we were perfect for each other, so...we did it!
Dad: Got married.
Gabe: Why do you keep saying that?
Mom: Haven't you had "The Talk" with him yet?
Dad: I haven't had the talk with PJ yet!
PJ (17): I'm good!
Also, there's some mild nudity - for example, Uncle Mel turns around (so his back is facing the audience) and pulls down his pants and underwear. His butt is covered with giant foam fingers (they're at a ball game), but projected onto a big screen for the entire stadium to see.
And the most nudity is in Snow Show (and all the commercials for it, too). PJ is completely naked, with his snowboard covering his private area. It's covered, but still who would want to see that? (Ok, who would want their siblings seeing that?)
There is some kissing but nothing over the top. So basically, I agree with abbyccga and buckets. Good, funny show but definitely unsuitable for many young kids.
