This isn't the best show on TV, but it's witty most of the time, and there are only a few TV-MA episodes. Some of them are TV-PG, and use little or no bad language except for using other words like "darn" and "shirt" in place of d--n and s--t. But with that said, violence would be used more instead of language.
I'm kind of confused here, because I only watched 2 episodes of the show, and they were TV-PG. Those episodes didn't have much sex, language, or anything that bad in them except for stealing and a kid who said "My uncle's porn smells like salmon." I guess I'll have to watch more.
