This was a funny show that appeals to adults AND children above the age of 10 at least. The reason why I say that, is because there are millions of children who have heard curse words and/or use them, whether in front of their parents or behind their backs.
This show has most of the words censored, which shouldn't make it much of a problem as far as language is concerned. There is no nudity, but there is references to anal rape("...If I drive under the influence, I could kill me, you, somebody's baby...Or worse, I could get arrested and go to jail and get anally raped") and/or homosexuality or the word "gay" which may or may not be offensive, but practically everyone knows and uses that word, and if you don't know you must not live in america.
It also contains the "N bomb". Now for black audiences, which is the larger intended audience that the show was actually made for, we already know what that word is, because it's in most black teenagers or black people in general's vocabulary and in most of their dialogue anyway. The reason why the show has these words is to place realism, and to relate, or let people who watch relate, to black people as well. If you want to guard a child from even the slightest hint of anything even REMOTELY bad in your opinion, then they are going to be crippled as human beings when they grow up. If you just tip toe around racy subjects and such, then how will the child react to these things when they get older?
There isn't any nudity, and if there was, it's only in the uncut episodes on DVD, so don't worry about that.
The closest things to sex were the above mentioned, and dialogue about a certain type of sex, references or involvement with prostitutes and pimps. But these things are possibly already known about if your child plays things like "Grand Theft Auto" and/or watches things like pornography. All I can say is, if your child has heard curse words from you or anyone else, just tell them not to use it, and it's okay in that regard. If your child has ever looked at or seen a girl that they liked, or even knows what a butt is, then language in that regard is okay. If the words "Pimps" and "Prostitutes" and any words related to those are in your child's vocabulary(and it probably is, unless you've been living under a rock with your family), they can watch it. If the word sex is in their volcabulary, or if they have ever read hospital tracts or had sex ed classes, then the word sex, which possibly may be the only word even close to sex besides the above mentioned things are okay. If your child attends history class, hangs around black youth at school, on the internet, or anywhere else, and if your child is black, white, or mexican, then the word "negro" or "n*gga" is already heard of, and they can definately watch the show because that word is the main thing placing it in the TV-MA category. If the above things beside that word were the only problems with the series, it'd have a PG-14 rating, and 13, or if your child watches family guy, then younger, if possible.
